SECTION I
GENERAL DESCRIPTION
The Neptune Series 560 “dia-PUMP” is a reliable metering pump of the hydraulically actuated diaphragm type.
Under constant conditions of temperature, pressure, and capacity adjustment settings, a plus or minus range of 1 %
metered discharge volume is maintained.
A plunger reciprocating at a fixed stroke displaces hydraulic fluid, which actuates a flexible, chemically inert, Teflon
®
diaphragm to create pumping action. The capacity of the pump is regulated by controlling the volume of hydraulic
fluid, which bypasses the diaphragm cavity.
Capacity adjustment can be made manually or automatically by instrument signal.
Metering accuracy is maintained by a control rod, which allows hydraulic fluid replacement and air venting
automatically with each stroke, while also taking into account temperature changes of the hydraulic fluid. Metering
accuracy is also insured by the use of double ball check valves on the suction and discharge ends of the pump.
PLEASE READ THE INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING THE PUMP.
