<p>#CMT# #/CMT# An air outlet from a cylinder air collection chamber can be sealed by a closure body connected to one end of a lever, the other end of the lever being connected to a counter-body resting on top of a flexible membrane. The lower side of the membrane is in open communication with the air chamber. #CMT# : #/CMT# The pump has at least one horizontal cylinder mounted in a casing (1) and each cylinder contains a piston with a supply line and an outlet line (2). At least one valve (3) mounted in the casing above the cylinder is used to seal the cylinder outlet line. Air from the cylinder is collected in at least one air chamber above the cylinder. #CMT#USE : #/CMT# For ventilating plunger pumps. #CMT#ADVANTAGE : #/CMT# The device can be used in plunger pumps with high variations in flow rate and pressure drop. The device is reliable, requires little maintenance and is self-regulating without the need for electr(on)ic control equipment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of part of the upper side of a plunger pump. 1 : Pump casing 2 : Outlet line 3 : Pressure valves.</p> |
