Reciprocating pumps diaphragm

Reciprocating Pumps There are three classes of reciprocating pumps piston pumps, plunger pumps, and diaphragm pumps. [Pg.910]

Positive displacement pumps, such as reciprocating and diaphragm pumps. [Pg.199]

The present essential aspect for the decision in favour of a Diaphragm Pump is its hermetical tightness, which is guaranteed by its stationary and therefore free of wear clamping area. The Diaphragm Pump is the only type of reciprocating pump where the dynamic sealing is not in contact with the fluid. [Pg.593]

Pump types P = piston reciprocating pump SD = simple-diaphragm reciprocating pump CD = diaphragm reciprocating pump with counter-piston. [Pg.24]

In a simple diaphragm (or membrane) reciprocating pump, the piston moves in an oil chamber which is separated from the solvent chamber by a thin diaphragm... [Pg.25]

Diagram of a simple diaphragm reciprocating pump, a = motor, b = drive mechanism, c = plunger piston, d = piston seal, e = low-pressure hydraulic chamber, f = safety device, g = high-pressure hydraulic chamber, h = diaphragm, i = solvent chamber, j = column check valve, k = to column, 1 = reservoir check valve, m = reservoir.

The dead volume of a diaphragm reciprocating pump is greater than that of a piston reciprocating pump, and can be several times the maximal volume swept by the membrane. [Pg.26]

The precision of both piston and diaphragm reciprocating pumps depends greatly on the efficient functioning of the reservoir and column ball check valves, which must be perfectly designed. They are made of stainless steel or, for miniTHal wear, sapphire. Sometimes the seats of the check valves are in sapphire and the balls in ruby. The pistons can be made of stainless steel, glass or sapphire. [Pg.27]
