SECTION I

GENERAL DESCRIPTION

The Neptune series 600 “dia-PUMP” is a reliable metering pump of the high-pressure 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.

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 of the

pump.

PLEASE READ THE INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING THE PUMP.
