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 Mechanically Actuated Diaphragm metering pumps should be located on a level surface. Four

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

pump should be supported to prevent stress on the pump inlet and discharge fittings.

1.0.3

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

Foreign matter 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 PORT 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 isolation 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

counterclockwise when viewed from the top of the motor or looking down on the pump. An arrow mark on

the side cover of the gearbox is indicating the correct rotation (Figure 1).

Operation with the incorrect rotation will damage the pump and motor.

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

1.0.7

Fill gearbox and pump by removing the breather and pouring the specified gear oil (drive lubricant) or oil

provided with pump through the Breather port. Pour oil in slowly until it covers the worm gear.

1.0.8

For dry pump (pump shipped from factory without oil) the oil volume is 27ozs (800cc) to fill the pump.
