About Pumps
PlumbersStock.com offers a variety ofdiscount pumps online. A pump is a machine that maneuvers fluid through your system (plumbing,HVAC,irrigation), from the suction tube to the discharge tube. We carry quite a few pump options so shop around and find exactly what you need.
Types of Water Pumps
There are pumps powered manually or by electricity, combustion engine, or wind power. In order for some pumps to perform the mechanical work, they will actually consume energy by moving the fluid through the system. There are many different types of pump systems, includingdisplacement, velocity, gravityand many more!
Displacement Pumps
Of the many pump options that we have, one of the most popular among customers is thepositive displacement pump. It forces water to move by capturing a set amount and displacing or shifting the trapped mass into the discharge pipe. Displacement pumps uses a cavity rather than a centrifugal or a rotodynamic pump, therefore this type offers aconstant flow. The displacement pump cannot have a closed valve on the discharge end because there is no shutoff head. If there were to be a closed valve the pressure of the fluid flow in the discharge pipe would eventually burst causing severe damage to the pump. The displacement pump isbuilt with a safety valve in the discharge line. This is also called a relief valve that can be external or internal. The external will usually have a line tracing back to the suction pipe or supply tank for extra safety measures, the internal valve is just used as a safety precaution. A variety of different water pumps are considered displacement, including:
- Gear
- Progressing cavity
- Plunger
- Screw
- Rope
- Flex impeller
- And more
Velocity Pumps
There is a range ofvelocity pumpsthe most common is theroto-dynamic pumpthat uses kinetic energy to increase the flow velocity. With this increase in energy there is a conversion to a gain in potential energy. A major difference between displacement and dynamic is that the dynamic pumpcan be safely operated under a closed valve conditions, for short periods of time. Within the velocity family there is also thecentrifugal pumpwhich uses a rotating impeller (basically a rotor inside a tube) to increase the pressure and flow rate of the fluid within the system. The following water pumps are velocity, including:
- Centrifugal
- Mixed-flow
- Axial-flow
- Radial-flow
- And more
Gravity Pumps
简单地说重力泵使用下坡流take water from far-underground aquifers in high areas to consumers at a lower elevation. The steam is powered by a steam engine (obviously, but without pistons). It is designed to move fluids without other moving parts. Since there are no valves in the valveless pump to regulate the flow of fluid it uses various biomedical and engineering systems.
