DIN-Standards Centrifugal End-Suction Pump

They are mainly used in installations requiring large flow rates, abnormally high working pressures (cast steel, S.G.iron) or special temperatures or pressures respectively. Their installation requires heavy foundations and extensive piping configurations. The high flow velocities within the pump body and the pump ports often require special noise attenuation measures.The following diagram depicts a sectional view of a flexibly-coupled end-suctionpump without motor, coupling and baseplate. 

Pump Designs in Building Services

In building services, especially for pumps for heating and air-conditioning technology, the classification of the pump design according to the sealing (wetting of the motor) is widespread:
DesignDescription
Glandless PumpGlandless pump with canned rotor motor
Glanded PumpCentrifugal pump with shaft seal
In addition, the subdivision according to the type of installation or the arrangement of the drive is common:
  • Monobloc with flange-mounted motor
  • DIN-standards with motor and coupling on common baseplate
