Product No.: On request

Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and radial discharge
port. The shaft, impellers and chambers are made of stainless steel. The inlet and discharge parts are made of cast
iron. The mechanical shaft seal is a special designed, unbalanced O-ring seal. Pipework connection is via internal
Whitworth pipe threads, Rp (ISO 7/1).

The pump is fitted with a 1-phase, foot-mounted, fan-cooled asynchronous motor.

Further product details

Pump and motor are integrated in a compact and user-friendly design. The pump is fitted to a low base plate, making
it ideal for installation in systems where compactness is important.
The state-of-the-art design and materials of the shaft seal ensure high wear resistance, improved sticking and
dry-running capabilities and long operating life.
Servicing the pump requires no special service tools. Service parts are in stock for quick delivery and are available as
kits, single parts or bulk. Service videos are available on www.youtube.com.

Pump
A combination of a stop ring and a Nord-lock® washer secures a tight and reliable fixation of the impeller spacing
pipes to the splined pump shaft. It is possible to remove and fit the hydraulic parts from the pump side. The inlet part,
chambers and discharge part are hold together by four staybolts.
The pump is fitted with an unbalanced O-ring seal with a rigid torque-transmission system. It has a fixed seal driver
ensuring a reliable rotation of all parts. The dynamic secondary seal is an O-ring.
Seal faces:
• Rotating seal ring material: aluminium oxide (alumina)
• Stationary seat material: carbon graphite, resin-impregnated
Carbon graphite against alumina is a good all-round seal for not too demanding applications. The corrosion
resistance is often limited in water to a range between pH 5 and pH 10. Usage in liquids above 90 °C is not
recommended. The seal can handle dry-running conditions for short periods.
Secondary seal material: EPDM (ethylene-propylene rubber)
EPDM has excellent resistance to hot water. EPDM is not suitable for mineral oils.

The pump shaft is connected to the motor shaft through a left thread and tight fit. The shaft cannot be dismantled.

Motor
The motor is a totally enclosed, fan-cooled motor with principal dimensions to EN 50347. Electrical tolerances comply
with EN 60034.
