Double Acting Plunger Pumps

Double acting plunger pump is plunger type dosing pump which the working fluid acts alternately on both sides of the piston. This is one that, as it fills one end of the liquid chamber, is discharging liquid from the other end of the chamber. On the return stroke, the end of the chamber just emptied is filled, and end just filled is emptied.

Each stroke of the piston fills one chamber and empties another, which nearly doubles the flow rate over a single-acting plunger pump. It also smooth in the flow and the basic principal of operation will be identical. This pump can be used for high precision injections with pulse rates of ±1%.

Have you ever seen a pulseless metering pump? You’ve never actually seen a pulseless metering pump, even though you may have seen similar pumps. You might have seen a pulse reduction pump, which reduces the pulse with pump piping or a built-in air chamber. However, SRS Pumps has successfully developed actual pulse-less pump technology. In the belief that we coexist with our customers, we will show you true essence of Pulseless Pump.
