For diaphragm pump,the reciprocating plunger deflects the diaphragm

through volumetric displacement of hydraulic fluid to realize the

suction and discharge of fluid by means of suction and discharge

valves.Diaphragm totally separates the metered fluid from the

environment and the hydraulic liquid. Diaphragm rupture signaling

prevents the pumped and hydraulic fluids intermixing in case of

diaphragm rupture.Under all operation conditions,the rupture of

diaphragm is reliably signaled and the pump driver may be shutdown. The

pump returns to normal after replacing the ruptured diaphragm.

Nuclear power station:
Chongqing Pump Industry Co.,Ltd.is an enterprise authorizede by the

state of developing and manufacturing the nuclear safety class 2

pumps.The top products among the nuclear safety class 2 pumps,the

charging pump/the HP safety injection pump and the hydrotest pump which

are developed by CQPI,mark CQPI's stepping toward catching up with and

surpass the advanced world levels of pumps for nuclear power station,and

creating the favourable condition for realizing the domestization of

nuclear safety class 2 and class 3 pumps.
