There are several ways to make a distinction between pumps

There are several ways to make a distinction between pumps: 

1.)   Whether they are driven by a crankshaft or wobble plate
2.)   How many cylinders
3.)   Whether they are piston (cup) or plunger pumps
4.)   The method of crankcase lubrication
5.)   Whether they have a hollow or solid crankshaft. 



A crankshaft pump which has three cylinders (triplex plunger pump) uses a crankshaft similar to that of an automobile's crankshaft. The plunger is driven by the wobble plate pump that replaces the crankshaft with a cam (plate).

Industrial Pumps

The pumps in the General Pump TSP Series are designed to deliver high pressures of up to 7,250 pounds per square inch depending on the model. Pumps in the TSF Series are designed to produce higher flow rates, with the most powerful model providing approximately 12 gallons per minute. In addition to being among the top performing pumps on the market, these units are also among the most durable and feature multi-year warranties as a testament to their longevity. Recognized for their reliability, all General Pumps from Water Cannon also feature lifetime guarantees on the manifolds. 

The manifolds of the TSP and TSF series pumps are brass forged and precision machined to stand the tests of time and extreme use. As further evidence of their survivability, even accidental freezing cannot warp these pumps. The pumps have an innovative seal design to extend seal life. The plungers on the pumps improve thermal shock resistance and the valve caps’ design improves hydrostatic performance. General Pumps' large capacity oil crank cases dissipate excess heat which extends the lives of these pumps significantly as well.

PUMP HP, GPM AND PSI



The amount of power required to drive a pump intensifies as the desired pressure and flow increases.  Also it generally requires a gasoline engine rated at approximately twice the horsepower of an electric motor to get the same performance out of the same pump under continuous operation.

To figure out what horsepower is needed to operate a pump at a certain, desired flow and pressure, you just have to multiply the GPM (gallon per minute) and PSI (pounds per square inch) and figures you want together and divide the result by 1450 to come up with the required electric motor horsepower for pumps. To roughly determine the required gasoline engine horsepower, just multiply the figure by two.
