Assembly

The pump must be bolted to an even, stable base. The base must be capable of permanently
bearing the weight of the pump. Bolt the pump with the four bolts (M8) through the four bore
holes in the frame into the pump feet or base if applicable.
When fixed, the pump must not vibrate.

Liquid end
WARNING
• The liquid ends may still contain traces of water from the factory tests! If using with
media which must not come into contact with water, ensure that the liquid ends are
dried before installation. Dry with compressed air. Then rinse out by inserting a suitable
rinse aid through the suction connection.
• The discharge line should be arranged to ensure that the maximum admissible pump
and system operating pressures are not exceeded during the discharge stroke.
NOTICE
• It is necessary to install a filter in the suction line for the piston liquid end if using with
media with particle sizes greater than 0.3 mm.
• Accurate metering is possible only at a constant back pressure above 1 bar.
If metering at atmospheric pressure, use a back pressure valve to generate a back
pressure of approx. 1.5 bar.

Leakage discharge (TZMb, TZMa and TZKa only)
Leakage fluid is drained off via the flushing collar and a hose nozzle. No other liquid end parts
come into contact with the fluid.
Connect a hose to the lower hose nozzle
Feed the hose into a leakage fluid bund.
