Mini-Gear Oil Pump 110v 450w 1/2 HP 8 gpm WCB30 WVO Fuel Transfer biodiesel WMO Sale Price: $285.00  |
|
Mini-Gear Oil Pump All Metal Pump This pump may be used for pumping oily liquids such as diesel, biodiesel or kerosene. It can pump vegetable oil with a continuous duty cycle if the oil is not too thick. Generally speaking, vegetable oil will need to be around 75° F or higher, depending on how thick it is for this pump to maintain a continuous duty cycle. This pump works excellent for biodiesel processor applications. It is not recommended for pumping heavy oils such as motor oil as the duty cycle is greatly reduced. The mini-gear pump is a pump attached to the motor by a shaft. The pump itself is all metal (metal gears) and can pump hot fluids without overheating the detached motor. The motor is high power and has thermal protection, which will automatically shut off the pump in case of the risk of overheating. These pumps create powerful suction and are self-priming. They can run dry for intermediate amounts of time, allowing for the use of a suction hose for collecting fluids from a tank. These pumps are so powertful they will actually pull and push air through the hose. The metal gears which drive the pumping action can handle a lot of fluids, even if partially dirty. In the case of vegetable oil, any soft particles will pass right through the pump wilth no problems, and are often pulverised by the gears themselves. Hard materials, such as metals, should not be allowed to pass through the pump to prevent damage. |

If you are looking to have an incredible camping experience, then having the right equipment is a must. And if you really want to have the most fun, then stay in a tent as opposed to an expensive cabin. But no matter where you stay, you had better bring the proper type of camping gear. And be absolutely certain that whatever gear to decide to bring will cover all of your needs.
The perfect example of a camping item that you might need is the foam sleeping pad. These unique and comfortable pads are the perfect sleeping companions when you are stuck sleeping on the hard ground. Yet another necessary piece of camping gear you should always take in addition to sleeping pads is a sleeping bag. You definitely want to be comfortable, but don't risk ending up freezing at night because you didn't bring a sleeping bag.
Although it's vital that you bring certain camping gear items, you also want to make sure that your caravan is working properly. There is nothing worse than getting stuck on your way to the campground. In addition, try to locate a camp site that fits your camping style. If there are camping sites close to your home, then that would be the best place to start. This is even more applicable if you are camping for the first time.
Once you have determined your camping location, then you need to make a checklist of gear that you will be taking. This is crucial so that you don't leave any necessary items behind. You should include the following items: flashlights, a first aid kit, sleeping bags, a tent, a sleeping pad, a portable fridge, and possibly a portable stove. Just don't forget to put the food and drinks you want into the fridge before you leave.
The final step is to plan some activities that will be fun for the entire family. Fishing, hiking, and swimming are activities that can be accommodated at most campgrounds and are all loads of fun. Just keep in mind that as long as you bring all of your necessary camping gear, the only thing you have to do once you arrive is start enjoying your camping experience.
If you are looking for great deals on a comfortable sleeping pad, then check out Jack's latest website. Here you will find a variety of top quality sleeping pads to help you sleep comfortably on any type of terrain.
Review of Aquarium (& Pond) Power Head Pumps
No to pick on about.com (mentioned them in an earlier post in Fish as Pets), however after an email form a hobbyist about aquarium power heads/pumps I thought I would investigate what is being said in reviews and stumbled across an article with the reviews of five different power heads.
Either they are from another planet or I must live in a parallel universe!
First they left off the list two of the best aquarium and pond power head/ water pumps then their reviews were quite contrary to my extensive experience with these pumps in literally 100s if not thousands of aquariums over the years in my aquarium maintenance business.
Here are six pumps I will review (including refutations of their comments):
*ReSun; this pump (power head) was totally left off their list, although not as well known in the USA/Canada they are very popular in Asia and Australia. ReSun has some sizes such as the #6 that are quite capable for very “mucky” pond environments and yet operate very well. The stainless steel coated impellers along with the ceramic shafts found on the larger models) are extremely durable and almost never fail.
These pumps are very reliable and start up without a problem; they also have very excellent head pressure (in fact among the best)! ReSun pumps can be submersed or place in line.
The models 3A, 5, and 6 are awesome in heavy duty applications such as ponds or very large aquariums where high flow and head pressure are necessary (as well as ability to deal with large amounts of particulates in the water).
About the only con is that with their heavy duty construction, these pumps can be somewhat noisier than some others (although still not bad here either). ReSun power heads are also not as adjustable in flow as some other power heads, but this a minor inconvenience IMO.
*Via Aqua; ; this is a real workhorse line of pumps that is VERY widely used in the professional aquarium maintenance community yet did not even get mentioned by about.com (go figure!). These pumps in the power head line (not the basic line) also have ceramic shafts and very durable construction. Via Aqua pumps (along with ReSun) can be used in sumps or as a power head and have excellent head pressure. The Via Aqua power head line (such as the VA 1300) can be submersed or used in line which adds to versatility that not all pumps can match. For Aquarium sumps (usually in marine applications) the Via Aqua 2600 and 3300 are unsurpassed in usefulness.
Again the only con is these pumps are a little noisy, but only when used in line (they are a little quieter than the ReSun line when submersed). Via Aqua power heads (as with ReSun and Rio) are also not as adjustable in flows as some other power heads, but this a minor inconvenience IMO. This inconvenience is more than made up for in versatility! I will also admit to a couple of models by Via Aqua that I not recommend due to less than desirable durability and these are the 2300 and 4900.
*Rio (by Taam); although no longer a preferred pump by me as the person who founded Rio started Via Aqua and improved on some of its problems. These are still excellent pumps IMO and although I partly agree with about.com with their assessment, I think they go overboard with their comments as to high maintenance. Rio power heads are very powerful with excellent head pressure (depending on the model).
The cons are the impeller (although very durable), seem to have problems in environments (especially ponds or dirty aquariums) that have a lot of debris and organics in the water column. However they still are very good at starting up when used as wave makers and are properly maintained. These pumps are also not adjustable in their flow
*Maxi Jet Power heads; I will have to agree the most with about.com on their assessment of these pumps. They are reliable and economical and start back up easily even when used as wave makers. However they do have their cons and that is they have poor head pressure and are not very versatile (unlike the Via Aqua, ReSun, and Rio pimps) as they are only power heads and nothing more.
*Penguin Power Heads; I do not generally agree with assessment by about.com on these power heads. Although they do have a neat feature with the reverse flow power head for UG filters (which are not very common anymore though), the other nice feature is the adjustable flow feature.
However nice these features are these power heads have a poor track record for reliability, they have very poor head pressure, and do not re-start well after the pumps have been in service for a while (in applications such as wave makers).
*Hagen Aqua Clear Power Heads; this pump is also over rated by about.com in my extensive experience with them. I have used more Aqua Clear power heads than ANY other (including the Via Aqua pumps I now generally recommend). When these power heads first came out they were industry leaders in design, however they are of 1980s technology IMO and although they are better than Penguins in reliability and head pressure, they still would stop and not re-start in many of my applications when power was even briefly interrupted, making them a poor choice for wave maker applications. Aqua Clear power heads also do not handle high organic/debris loads well and need more maintenance than the Rios that about.com claimed needed!
Bottom line with Aqua Clear power heads is that they are reasonable “retro” pumps, but certainly NOT the latest in technology!
*ZooMed Power Sweep; even though I sold these in my business, I rarely recommended them. They are basically a gimmicky power head with poor head pressure and low output. They are not real durable and the “sweeping” directional output feature is run by cheap plastic gears that often fail. These pumps do not handle high bio loads well and are best used in small aquariums or better vivariums where not much is asked of them.
SUMMARY:
I have had persons also ask me why many brands such as Via Aqua are not as commonly available as Hagen and does that make them of lower quality as no one really wants them?
The answer is quite simple; Hagen is sold through a larger network of mainline Pet Store distributors (although they are now transitioning to their own in house distribution system). This system promotes an all or nothing approach to marketing their products basically meaning you carry the whole line (good and bad) or not get discounts or even sell anything at all. This marketing system has been very successful (not to mention slick packaging), however this does not mean a better product.
Via Aqua (among many other high end brands) does not sell through traditional marketing distribution methods and systems, rather it sells many high end Marine fish importers and similar without all the expensive marketing gimmicks. This in particular places their products in the hands of Aquarium Maintenance Professionals who do not care about slick marketing or whether it is the fad, rather whether it works or not which is why Via Aqua and many other similar high end companies choose to sell this way.

REVIEW OF AQUARIUM (& POND) POWER HEAD PUMPS BASED ON REAL WORLD EXPERIENCE

Why gear pump can not be used for water lifting with positive suction?
From your question, and, if the pump has a positive suction pressure, it appears that the problem lies in worn teeth of the gear wheels and of the pump casing due to erosion from solid particles carried in the liquid being pumped.
Any gas or air drawn into the pump with the liquid, will normally be carried through with the liquid and will not cause cavitation. This action of the pump means that it's a 'Self Priming' pump. The discharge pressure may however, fluctuate.
The output from this type of pump is directly proportional to the speed of operation. If the speed is doubled, the output will be doubled and the pressure will have very little effect. (At higher pressures, due to the fine clearances between the teeth and between the casing and the rotors, a small leakage back to the suction side will occur resulting in a very small drop in actual flow rate. The higher the discharge pressure, the more likely that internal leakage will occur).
The pump is capable of very high pressures if in good condition. (Certainly many more times higher than 14.7psig)
The substance being pumped (Liquid or Gas) has a lubricating effect within the pump. Using an internal lubricant will cause contamination of the fluid being pumped.
(The pump should have a discharge safety valve to protect against overpressure. If your pump has such a facility, check it out, it may be passing. (The safety valve is often piped to discharge back to the suction line or to the source of the liquid and, if it's passing, you may not be aware of it)..
2000 Holden Commodore VT Series 2 Acclaim review from Australia and New Zealand
What things have gone wrong with the car? ABS module failed at 220000, and again at 234000. Very common on Commodores this age. Airbag light came on. Reset with dealer computer; no further problems.
