In-line centrifugal pump 

HVAC efficient solutions for comfortable conditions

To be comfortable in a building, both at home and at work, an optimal climate control is important.

This can only be achieved with modern Building Management Systems in combination with the right pumps, in order to get an efficient distribution of water.


For a complete HVAC solution DP Pumps provides an extensive range of HVAC centrifugal (norm) pumps, Split case double suction centrifugal pumps, Mono-block centrifugal pumps and In-line centrifugal pumps. Also a wide range of small circulator pumps for heating and hot water is available.

The range consists of four types:

  • DPNT Norm centrifugal pump
  • DPAS Split case double suction centrifugal pump
  • DPNL In-line centrifugal pump
  • DPNM Mono-block centrifugal pump

The DPNL In-line centrifugal pumps are designed for heating and air conditioning applications. The DPNL series provide easy installation, especially in buildings where limited space in length is available.

For the different HVAC applications, various material options (cast iron, bronze and stainless steel) are available. The DPNL motors are suitable for variable speed operation.
