INTRODUCTION
Acromet metering pumps are designed and manufactured for long, low maintenance
service life and when properly applied, will give many years of consistent accurate
metering and trouble free operation.
The following instructions should be read and followed to correctly install and operate
the pump and ensure optimum pump life and performance.
Sectional arrangement drawings and Part Lists are enclosed at the end of this manual.

INSTALLATION
3.1
It is desirable to locate the pump as close as possible to the supply source
(eg tank) in order to minimise friction losses in the suction line.
3.2
The pump should be located with sufficient free space provided around the
pump to allow access for:
Adjustment of the manual capacity adjustment device;
To facilitate ease of routine and breakdown maintenance.
3.3
The mounting surface should be even and level. The pump base (mounting
plate) is provided with four (4) holes for mounting bolts.

PIPING
4.1
General
4.1.1
The pump suction valve is located at the bottom of the pump head
and the discharge valve on top. The pump cannot operate without
these valves and for correct operation, valves must be vertical.
4.1.2
Discharge pressure should be more than 20 kPa greater than suction
pressure to prevent over feeding or syphoning and to maintain
metering accuracy.
NOTE: When the difference is less than 20 kPa, a back pressure valve
and pulsation dampener should be installed in the discharge
line.
pump and valve, as close to the pump as possible.
4.1.3
A characteristic of reciprocating pump performance is pulsating flow.
Piping should be sized for flow rates at least 3.5 times greater than
maximum capacity of pumps.
NOTE: Small diameter piping will produce unpredictable flow rates
and system pressures.
