Caution: Damage due to incorrect seal material
The pump must use a mechanical seal constructed with
Viton elastomer if pump is moving oil. EPDM will shrivel
in the presence of oil and will cause the mechanical seal
to fail.

Functionality
Application
The purpose of the pump is to
pump the liquids specified in the
technical data for the building services industry
and industrial plants. Pumping different liquids
and exceed-ing the limit values specified in the
technical data may destroy the pump.
Functions
Design:
The pump is a single-stage circulating pump
with an inline design. It is driven by an electric
motor according to the NEMA standard.
Performance Regulation:
External pressure sensors and an external
control unit can be connected to the suction
side and the discharge side by means of a
pressure gauge tapping. The motor speed
can be controlled using an external frequency
converter.
Directions of Flow:
The arrow on the volute indicates the direction
of flow.
