Specifications of S-FP Sanitary Pumps

Semi-Open ImpellerSemi-Open Impeller
All pumps are optimised according to requirements.
Electro-polished stainless steel impellers are suitable for both low-viscosity and particle-laden liquids.
Holes through the impeller serves to equalize pressure on both sides of the impeller.

Volute CasingVolute Casing
Adjustable outlet 360º.
The unique design ensures that the outlet can be rotated 360° in all directions which makes it easy to fit into any installation.
The volute is built into the pump house behind the impeller. This ensures a low noise level and careful handling of the media being pumped.
Volute Casing


  • The impellor, the motor frame and back plate conform to the requirements of EHEDG.
  • The internal surface finish is 0.5 µm to 0.8 µm Ra.
  • All internal pathways have been designed to respond exceptionally well to CIP to ensure “peace of mind”
    throughout any cleaning in place activity.

Mechanical Pump Seals
Mechanical Pump SealsA user-friendly cartridge seal makes it possible to change the seal without using any special tools or personal with specific skills.
Ease of installation reduces downtime and mistakes.
The cartridge seal can be a single or a double mechanical seal.
Single mechanical seal: water, beer, milk and other non sticky liquids.
Double mechanical seal: sugar, syrup and other sticky liquids.
The double mechanical seal is designed to prevent the pump from running dry and to handle products that have a tendency to crystallise and/or form carbon.
To simplify and to minimise on the cost of the spare parts required, the S-FP pumps share the same mechanical shaft seal. This combined with the ease of servicing reduces the maintenance costs.

Sanitary Pumps High Efficiency MotorsHigh Efficiency Motors
The high quality electric motors are manufactured according to international standards IEC 60034-30 and conform to the requirements of the EC Directive 2009/125 (eco-design for energy-related products).
The standardised design of the Shaft and Back Plate makes it easy to change the motor size in the event that the pump duty changes. This makes the S-FP Pump the most flexible pump on the market.
