3. Product description

3.1 Product introduction

This manual includes instructions for installation, operation, and
maintenance of Grundfos SP submersible pumps with 0.5 to 250
Hp motors.

3.2 Applications

Grundfos SP submersible pumps are suitable for the following
applications:
• groundwater supply to waterworks
• irrigation in horticulture and agriculture
• groundwater lowering (dewatering)
• pressure boosting
• industrial applications
• domestic water supply.
The pump must be installed so that the suction interconnector is
completely submerged in the liquid. The pump can be installed
horizontally or vertically. See section Positional requirements.
3.2.1 Pumped liquids
The pumps are designed for pumping clean, thin, non-explosive
liquids without solid particles or fibers.
The maximum sand content of the water must not exceed
50/100/150 ppm. A larger sand content may reduce the life of the
pump and increase the risk of blockage.
Pump type
SP 5S - SP 25S
SP 35S - SP 77S
SP 85S - SP 300S
SP 385S - SP 1100S
When pumping liquids with a density higher than water
3
(62.3 - 62.4 lb/ftm ), motors with correspondingly higher
outputs must be used.
If liquids with a viscosity higher than water are to be pumped,
contact Grundfos.
N AISI 416 and R AISI 904L grade stainless steel pump sets are
designed for liquids more aggressive than drinking water.
For the maximum liquid temperature, see section Motor cooling
requirements.
