Reduce costs with a highly efficient SP pump
The Grundfos SP submersible is a highly durable pump made of high-grade, corrosion-resistant stainless steel. Resistant to sand and aggressive water, SP also boasts features such as dry-running protection and motor burnout protection, both of which contribute to the impressive durability of the pump.
Thanks to the optimised hydraulics design, the SP delivers optimum efficiency during periods of high demand, ensuring low long-term costs and high operating reliability. The pumps are suitable for a variety of applications, including groundwater supply to waterworks, irrigation, groundwater lowering, pressure boosting, and industrial applications.
Can the SP pumps also be operated in a horizontal position?
SP submersible pumps with a Grundfos or other submersible motor can be operated in any position from horizontal to vertical. The motor is arranged below the pump. A cooling jacket is generally required for these installation positions.
What does water hammering mean, and what causes it?
Water hammering is a pressure surge caused by a rapid change in flow velocity in the pipeline. This phenomenon is referred to as "water hammering" because the pressure surges are frequently accompanied by a noise that sounds as if the pipeline were being pounded with a hammer.
In well installations, water hammering generally occurs if a) the non-return valve in the downpipe extending down from the pump is installed more than 9 m above the water level, or b) the non-return valve ...
