SECTION I

GENERAL DESCRIPTION

The Neptune Series 7000 Mechanical Diaphragm metering pump is a reliable me tering pump of the Low-pressure
diaphragm type. Under constant conditions of temperature, pressure, and capacity adjustment settings, a +/- 2%
metered discharge volume is maintained. Rugged contoured composite diaphragm designed for high mete ring
accuracy over a full 10:1 turndown range.

A plunger reciprocating at a set fixed stroke, actuates a flexible, chemically inert, Teflon faced diaphragm, to create
pumping action. Screwing in and out a hand knob regulates the capacity of the pump. Screwing in (shortens the
stroke length) reduces the volume and screwing out increases it. A percentage of flow is read on the scale.

Precision-engineered liquid ends meters mild solutions, aggressive chemicals, high viscosity polymers (up to
5000cP) and slurries (hydrated lime slurries up to 4 lbs of /gallon of water, activated carbon slurries up to 1 lbs
/gallon of water)

Metering accuracy is maintained by the ball check valves at the suction and discharge of the pump. The use of screw
in cartridge ball check valves eases maintenance.

Temperature limitations on the plastic heads are 36 – 125°F (2 - 52°C)
Mechanical diaphragm pumps are positive displacement reciprocating pump s. Each pump consists of a power end

and a process end separated by mechanically operated Teflon faced diaphragm. Individual pumps will vary in
appearance due to various liquid ends; however, the basic principles of operation remain the same.
