SECTION I

GENERAL DESCRIPTION

The Neptune Series 6000 “dia-PUMP” is a reliable metering pump of the high-pressure diaphragm type. Under

constant conditions of temperature, pressure, and capacity adjustment settings, a +/- 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.

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. Meter-

ing accuracy is also insured by the use of double ball check valves on the suction and discharge of the pump.

PLEASE READ THE INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING THE PUMP
