Description
1.5 kW PQS Supreme S1 self-priming pump – 25.5 m³/h
The 1.5 kW PQS Supreme S1 pump is a single-phase self-priming pump designed to filter and recirculate water in high-volume swimming pools. It delivers a flow rate of 25.5 m³/h at 8 m.w.c., making it the highest-performance model in the Supreme S1 range.
It features a transparent lid on the prefilter basket, allowing the basket's condition to be checked quickly and making cleaning easier. Its IP55 protection improves resistance to dust and water splashes, while its low noise level helps reduce disturbance in the technical area.
The mechanical seal made of AISI 316 stainless steel increases resistance to corrosive environments and allows use in swimming pools treated with salt electrolysis. The pump supports a maximum suction height of 2.5 metres.
The model 110640150 is especially suitable for large private swimming pools and installations requiring high recirculation capacity, always combined with a correctly sized filter.
Available in different power ratings and flow rates.

Frequently asked questions about the PQS Supreme S1 1.5 kW pump
What flow rate does this pump deliver?
Model 110640150 delivers a flow rate of 25.5 m³/h at a total dynamic head of 8 m.w.c., according to the manufacturer’s technical data sheet.
Is it compatible with saltwater pools?
Yes. It features an AISI 316 stainless steel mechanical seal and is specified as compatible with saltwater electrolysis systems.
What does IP55 protection mean?
It indicates protection against the ingress of dust in harmful quantities and against water jets. This does not mean that the pump can be submerged or installed without protection.
Does it include a prefilter?
Yes. It includes a prefilter basket with a transparent lid to retain leaves and other debris before they enter the hydraulic body.
What is the maximum suction lift?
The manufacturer specifies a maximum suction lift of 2.5 metres, provided that the installation is watertight, correctly sized, and the pump has been primed.
Is it a single-phase pump?
Yes. The Supreme S1 range indicated in the technical data sheet is single-phase.
How do I choose a compatible filter?
The filter must handle, at a minimum, the pump’s operating flow rate. For this model, it is advisable to use a filter with a capacity of at least 25.5 m³/h under the installation’s actual conditions.
