  High-grade product, with all wetted parts produced in pressed stainless steel AISI 304.
 
 
  Reliable operation with excellent corrosion resistance
 
 
  High efficiency and long working life. Minimum maintenance required.
 
 
  Suction & discharge connections are 'in-line'. No mechanical stress on hydraulic parts.
 
 
  Low operating noise level.
 
 
  Small floor space required for installation. Space saving.
 
 
  IP 55 (protection) motors installed as standard.
 
 
  Mechanical seal in accordance to DIN 24960.
 
 
  Low speed (1 425 rpm) version available - Low noise level, long working life.In numerous occasions demands are set in relation to the noise level of pumps, especially for applications in residential housing. DP Pumps developed a low-speed pump. Both DPV14 & DPV24 are coupled to 1425-rpm motors, not only producing a particularly low operating noise level but also guaranteeing an extra long working life.
 
 
 
Suitable for handling clean water and non-aggressive 'watery' liquid compatible to materials of pump wetted parts.
