Note! Product picture may differ from actual product

Product No.: 95112936

The pump is designed for intermittent and continous operation in submerged installation. The three-channel impeller
handles solids up to 110 mm in size.
A SmartTrim impeller clearance adjustment system makes it possible to maintain maximum performance throughout
the lifetime of the pump.
To facilitate easy transportation as well as installation on-site, the pump is fitted with a robust lifting bracket. For
installation on auto coupling, the Grundfos SmartSeal gasket system provides a leak-proof connection. Pipework
connections are via a DIN flange.
Further product details
Pump
The channel impeller is of a semi-axial design with extra long vanes. This provides maximum performance and
prevents fibres and rags from getting caught in the impeller.
The bottom part of the channel impeller features specially designed auxiliary vanes which keep the impeller clean at
all time. These vanes are designed to create a powerful flow that keeps the clearance between the impeller and the
pump housing free from solids or fibres.
This pump is equipped with the unique SmartTrim impeller clearance adjustment system that enables easy restoring
of factory-set impeller clearance.
By tightening the adjustment screws on the exterior of the pump housing, peak pumping efficiency can be
maintained.
This can be done on site, quickly and easily, without dismantling the pump and without using special tools.
The shaft seal consists of two mechanical seals that ensure a reliable sealing between the pumped liquid and motor.

- Primary seal: silicon carbide/silicon carbide (SiC/SiC)

- Secondary seal: silicon carbide/carbon
The shaft seals have no springs or other parts in direct contact with the pumped liquid that prevents rags and fibres
from getting caught.
Furthermore, the shaft seals are bidirectional, meaning that they can operate in either direction thus allowing for
opposite rotation caused by backflow of liquid through the pump.
The pump is equipped with heavy-duty, maintenance-free, greased-for-life bearings. The main bearings consist of
double-row angular contact ball bearings whereas the support bearings are single-row deep-groove ball bearings.
The pump discharge flange is mounted with the Grundfos SmartSeal auto-coupling gasket, that provides a
completely leak-proof connection between the pump and the base unit of the auto-coupling system. This optimises
the efficiency of the entire pumping system and keeps operating costs at a minimum.

Motor
The motor is supplied with a 10 m power cable with protection sleeve and a free cable end. The pump is equipped
with the following motor protection and sensors:
- Three thermal switches (Klixon) for protection against overheating, one incorporated in each motor winding.

- A moisture switch fitted in the terminal block for continuous monitoring of the motor. If moisture is detected in
the stator housing, the switch will automatically cut off the power supply.

Moisture sensor: Y
Water-in-oil sensor: N
