2.2 General information
Ponndorf Hose Pumps are a self-priming positive displacement pumps without any glands
or valves. The pumping medium only comes in contact the inner surface of the pump hose,
but not with the moving parts of the pump. Therefore the pumps are particularly suitable for
pumping aggressive, abrasive and viscous liquids, but as well for pumping liquids
containing coarse-grained solids and sensitive materials which require to be pumped
gently.
Priming and pumping of combustible gases or fumes is prohibited.
Start-up and shutdown processes which require this should only be rarely
and kept as short as possible. Dry running of the pump (operation without
the pumping media) must generally be avoided, apart from the start-up and
shutdown processes mentioned before.
The operator must ensure that the relevant safety regulations (e.g. TRGS
727) for the pumped medium are observed to avoid dangerous electrostatic
charging. Among other things, please consider flow velocities, etc.
Hose pumps are only intended to pump free-flowing liquids but not to pump
gaseous pumping media.
The functioning of a hose pump can lead to abrasion on the pump hose. For
applications in which the possible abrasion is intermittent or not permissible,
appropriate filter technology must be provided by the customer.
To guarantee the tightness and chemical compatibility of the pump hoses,
the manufacturer of the hose pump must be consulted in case of possible
changes of the pumping media unless this information does not appear from
available documents.

To avoid blockages of the pumps and/or any other damages of pumps or
pump hoses, the operator must guarantee that no hose damaging objects
can invade the hoses (e.g. sharp-edged or too big and not pumpable
objects). A suitable strainer may be used as protection.

6.3 Mechanical connection
The nominal width of the tubing at the suction and the discharge side
should be approx. 25 % bigger than the nominal width of the pump hose.
The size of the hose pump is concurrent to the width of the pump hose.
The tubing on the suction side must be vacuum proof (reinforced) and the tubing on the discharge
side must withstand the maximum pressure of the pump. By using a pole changing switch the tubing
on suction and discharge side must withstand the maximum pressure of the pump.
Always use flexible tubing to connect
the pump with the pipework of your application.
The length of the tubing should be
at least 1 m. (see fig. 6.3.1).
The standard way of connection is flexible tubing (fitting the connecting sockets of the
pump), fixed with hose band clamps. Other options (e.g. threaded connections, Kamlok
couplings, standard flanges) are available on request.
In order to avoid pressure peaks, which can cause damages of the pump hose, there
should no pipe bends or 90° elbows be installed directly after the pump on the discharge
side (please see fig. 6.3.2 and 6.3.3).
Furthermore the cross section of the pipework on the discharge side should not be reduced
(please see fig. 6.3.4).
