SPECIFICATIONS

PUMP

The SV pump is a non-self priming vertical multistage pump coupled to a standard motor. The liquid end, located between the upper cover and the pump casing, is held in place by tie rods. The pump casing is available with different configurations and connection types.

  • Delivery: up to 160 m3/h.
  • Head: up to 330 m.
  • Temperature of pumped liquid: from -30°C to +120°C for standard version.
  • Maximum operating pressure:

– 1, 3, 5, 10, 15, 22SV with oval flanges: 16 bar (PN16) at 50°C.

– 1, 3, 5, 10, 15, 22SV with round flanges or Victaulic®, Clamp or DIN 11851 connections: 25 bar (PN 25) at 50°C.

– 33, 46SV: 16, 25, 40 bar (PN 16, PN 25 or PN 40) at 50°C. – 66, 92, 125SV: 16 or 25 bar (PN 16 or PN 25) at 50°C.
