Monobloc / Inline Centrifugal Pump

The pumps can be directly pipe mounted or, if necessary, be separately supported by foundations or brackets.The high continuous temperature rating (up to 140°C) and the vibration-free operation on account of respectively shaped pump housings, impellers and drive motors are the decisive design features of this, especially for building services developed pump design. Low flow velocities through the housing as well at the pump ports make special noise attenuating measures (flexible connections) superfluous.

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
