GENERAL DESCRIPTION

Neptune Chemical Pump Company’s Glycol Feed System is intended for the automated

addition of glycol into closed loop chilled and hot water systems. The Glycol Feed System

automatically maintains pressure in the loop by adding glycol solution to make up for

losses, which occur due to leakage.

Glycol addition is controlled by a pressure switch with adjustable low and high set points.

When the pressure in the loop reaches the low set point, the pump begins to feed glycol

into the system until the high set point pressure is achieved and stops the pump.

MODELS

The Model G-50-1 or G-100-1 is provided with a 50 or 100 gallon polyethylene tank

mounted in a steel frame, 1.5 gpm bronze rotary gear pump (optional 3.0 gpm pump), float

switch and NEMA 4X control panel. The control panel features a HAND/OFF/AUTO

selector switch for the pump motor, ON indication light for the pump, LOW tank level

indication light and power cord with plug (115V, 60c). The pump suction piping includes

a PVC ball valve and cast iron “Y” strainer. The pump discharge assembly includes a PVC

ball valve, brass check valve, pressure switch, bronze relief valve and pressure gauge.

The Model G-XX-1A is identical to the G-XX-1 and has the addition of an audible

alarm, as well as light for low level tank indication.

The Model G-XX-2A is capable of feeding glycol to two separate closed loop systems

and includes two separate pumps, as well as suction and discharge assemblies.

The LP designation at the end of a model number (ex. G-XX-1-LP) indicates that a 3.0

gpm pump has been provided in place of our standard 1.5 gpm pump.

All glycol systems are provided with a dry contact for remote alarm.
