SP pumps with priming tank

 

SP self-priming pumps

  • Flow-rates up to 90 l/min and heads up to 43 m w.c.
  • Savino Barbera proprietary seal.
  • Maximum suction lift: – 5 m.
  • Plastic materials: PP, PVC, PVDF.
  • With a PVC single-chamber priming tank.

 

SP self-priming centrifugal pumps

The SP models are traditional Savino Barbera horizontal pumps, but yet equipped, in the suction line, with
auxiliary single-chamber priming tank maintaining a positive head (liquid level above the centerline of the
pump). This additional priming pot simply provides a flooded suction to the pump. As a result, a conventional horizontal pump will acquire self-priming capability.

The range of SP horizontal centrifugal pumps guarantees flow-rates from 1 to 90 m³/h and heads up to 43 m w.c.
(meters water column). Maximum negative suction lift: – 5 m. The curves refer to tests with clean cold water
(ISO9906). The performance can vary based on the different characteristics of the pumped liquid (pressure of
vapor, foam, temperature…).

Corrosion resistant plastic materials

All wetted parts in our pumps are strictly made of corrosion resistant plastic material. Selecting the most suitable chemically-inert polymers is indeed one of the main skills of Savino Barbera. Our choices have always been focused on the specific use that our industrial products are intended for.

  • Main thermoplastic materials: PP, PVC, PVDF.
  • One-piece plastic impellers without any metal insert.
  • Shafts with heavy-wall plastic coating.
  • Guide bushings made of charged PTFE, Ceramic or SiC.

The main materials include some highly corrosion resistant polymers: PP, PVC, PVDF.
