INSTALLATION INSTRUCTIONS

1.0 GENERAL

1.0.1 UNPACKING & INSPECTION

When unpacking a pump or chemical feed system, be certain that no parts are thrown away.

Examine the equipment for possible damage. If damage has occurred, file claim with the common

carrier within 24 hours. Neptune will assist in estimating the repair costs.

1.0.2 The Mechanical Diaphragm metering pumps should be located on a level surface. Three mounting

holes are provided to anchor the pump securely to the mounting surface. All piping to the pump

should be supported to prevent stress on the pump input and output fittings.

1.0.3 Before connecting the pump make sure that all fittings are completely clean by flushing thoroughly.

Foreign matters with sharp edges entering the pump can damage the diaphragm and severely limit

the life of the pump.

1.0.4 A “Y” STRAINER (AT LEAST ONE PIPE SIZE LARGER THAN SUCTION INLET SIZE OF THE

PUMP) MUST BE INSTALLED IN THE SUCTION LINE OF THE PUMP TO INSURE AGAINST

FOREIGN MATTER ENTERING THE PUMP

1.0.5 It is recommended that shut-off valves and unions be placed in the suction and discharge lines if

possible. Such an arrangement will facilitate servicing the pump.

1.0.6 The electrical supply to the pump must match the motor nameplate characteristics. The motor

rotation is counter clockwise when viewed from the top of the motor or looking down on the pump.

An arrow mark on the gearbox shows the rotation (See Figure 1)

IMPORTANT

On single-phase units, the rotation is set at the factory and must not be changed.

FIGURE 1

Please note Figure 1, indicating the correct rotation. Operation with the incorrect rotation will

damage the pump and motor.

1.0.7 Fill gearbox and pump by pouring the specified gear oil (drive lubricant) supplied through the

Breather (see note) at the rear of the pump. Pour fluid in slowly until it covers the worm gear.

PLEASE NOTE: Oil may be poured through breather. Snap off the breather top and remove the breather

sponge to fill oil and then reinstall sponge and breather top.
