Installation And Setup; Mechanical Connection; Installing The Pump Hose (Px Models Only) - PONNDORF PX Notice D'utilisation

The installation is dependent on the pump type and can be made stationary or portable.

Mechanical Connection

The diameter of the suction and discharge hoses should be approximately 25% greater than that of the pump hose. The
type of pump = nominal diameter of the pump hose in millimeters. (Example: PX27 = 27 mm ID Hose, etc.)
The suction hose must be vacuum-proof and the discharge hose must withstand the maximum pressure of the pump.
There must always be a flexible hose of 0.5 – 1 m between the pump and any rigid system piping. (Standard connec-
tions are hose barb type.) Threaded connections, camlock couplings or flanges are also available. Contact factory for
details.
CAUTION: Positive displacement pumps should always be fitted with a relief valve on the discharge.
Otherwise, the pump could be damaged if the maximum pressure is exceeded.
Installing the Pump Hose — PX Models Only
NOTE: Before installing the hose, make sure the outside of the hose is adequately
greased. (See REPLACEMENT PARTS manual for special grease.)
WARNING: Isolate the pump from the main power source before connection,
assembly or maintenance.
1. Remove the flanges on the suction and discharge sides. Liberally lubricate the outside
of hose with special grease.
2. Turn on the power and start the motor briefly. The rotor will pull the hose in as it
rotates. As soon as the end of the hose appears at the discharge side, stop the motor
and turn off the power.
WARNING: Do not wear gloves or loose clothing, as they can be pulled in.
3. Put the sealing ring onto the flangeless end of the hose, and insert the connecting
sockets into the ends of the hose on both the suction and discharge ends.
4. Screw the suction and discharge flanges back on the pump.
The pump is now ready to operate.
WARNING: Before operating the pump, all valves in the pipe work must be opened.
A hazardous bursting condition could develop and/or the excessive
pressure will damage the pump and hose and may cause harm to
personnel.
