WARNING
• EX pump only: Always observe the "Important supplements for dosing pumps in
EX areas" section of the "General operating instructions for ProMinent dosing pumps
and hydraulic accessories"!
CAUTION
• Danger of burns from hot power end motor in the event of a fault!
NOTICE
• The pump is designed to meter liquid media within the stated capacity limits.
• Note the limitations regarding high viscosity or density of the medium.
• No life-threatening metering chemicals to be used with piston liquid end. Because of
their manufacturing method, piston liquid ends are never hermetically sealed!
• Ensure that the liquid end materials are resistant to the feed chemical. (See ProMinent
resistance list in the Product Catalogue or on www.prominent.com)
• The pump must be operated in accordance with the operating conditions stated in the
"Technical data" section.
• 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.
• Only TZHa: If no hydraulic oil flows through the hose to the bleed valve, switch off the
pump immediately and contact customer service.
• Before commissioning the pump, connect the overpressure sensor and the diaphragm
rupture sensor.
• The pressure control valve (TZHa) is designed to protect only the motor and the gearbox
against inadmissible overpressure caused by the pump.
• The pressure control valve (TZHa) must not be used to bypass metering stoppages while
the pump is running. It is a safety element.
• Do not use the pressure regulating valve (TZHa) to protect the system. It cannot protect
the system.
IMPORTANT
• It is possible to adjust the stroke length when the pump is at rest only when the liquid
ends have been depressurised.
• If the diaphragm rupture warning system signals a diaphragm rupture, you may continue
metering for a short period at your own risk. However, metering reproducibility is
impaired.
10 mm = 100 % stroke length
(10 turns)
On the stroke adjustment wheel:
1 turn = 10 %
1 long scale division = 1 %
1 short scale division = 0.5 %
6.3 mm = 63 % stroke length
(6 turns and 3 long scale divisions)
