High Pressure Pumps
What is a high pressure pump?
If you have a liquid that you need to pressurize to a high pressure, there are countless options available. Most categories of pumps — including positive displacement pumps, rotary pumps and reciprocating pumps, and centrifugal pumps — contain both low-pressure and high-pressure types. But in general, pumps that best harness the laws of physics are best equipped to generate high levels of pressure. It’s also important for a high pressure pump to have very low clearance between their moving parts and the walls of the pumping chamber.
The amount of pressure generated by a pump depends on three main factors:
- the amount of external power applied to the pump
- the mechanism used to drive the pump
- how well the pump is sealed.
Most reciprocating pumps, for example, harness the power of suction to draw liquid into a chamber before forcing it out in a different direction. The pressure with which the liquid is forced out depends upon the amount of power applied to the piston, diaphragm, or plunger that contracts the pumping chamber.
Other examples include centrifugal pumps, which use the law of centrifugal motion; velocity pumps, which harness the first law of thermodynamics; and booster pumps, which use electricity to boost the liquid's pressure.
Wilden offers a reliable and rugged high pressure pump capable of moving solids laden slurries and viscous fluids at high pressure. The pump is used in paints and coatings, chemical sludge transfer, food processing and other related applications. In addition, the product is available in ductile iron, stainless steel, and aluminum material, and allows for a max flow rate to 95 gpm. Wilden’s high pressure pump has a lube-free operation and can deliver pressure up to 221 bar (3200 psig).
So now what do you do? As many of you know, this is a fairly common occurrence, particularly with pumps that have been around a long time. Here's some advice on what to do.
