The INOXPA PROLAC HCP SP is a self-priming hygienic centrifugal pump designed for applications where liquids contain entrained air or gas. Its design allows the pump to maintain stable pumping performance without loss of capacity, making it particularly suitable for CIP return duties and similar processes.
Once initially primed with liquid, the pump automatically evacuates air or gas from the suction line during operation. The self-priming function removes the need for vacuum pumps, foot valves or additional pipework, simplifying system design and installation.
Depending on size and configuration, the PROLAC HCP SP range offers flow rates up to 110 m³/h with differential heads up to 60 m.
The PROLAC HCP SP pump is intended for hygienic process environments where air-entrained liquids must be transferred reliably.
Its primary application is CIP system return, where cleaning solutions often contain air. The pump is also suitable for food processing, pharmaceutical and selected chemical applications where hygienic design and resistance to chemical attack are required.
The PROLAC HCP SP pump is suitable for pumping low viscosity hygienic fluids that may contain air or gas, such as CIP solutions, process water, cleaning chemicals, beverages and similar liquids.
Its gentle centrifugal action ensures stable handling of products without excessive shear.
The PROLAC HCP SP operates using a self-priming centrifugal principle. During start-up, the pump draws air or gas from the suction line and mixes it with liquid contained within the pump body.
The resulting mixture is directed towards an integrated separator tank, where the liquid and gas separate due to reduced velocity and gravity. The liquid returns to the pump body through a return pipe, while the air or gas is discharged through the outlet. This process continues until all air is removed from the suction line and the pump operates as a standard centrifugal pump.
To maintain self-priming performance, it is important that discharged air can escape freely without back pressure.
The PROLAC HCP SP shares the same core components as the PROLAC HCP pump, including the impeller, mechanical seal and motor arrangement. The key difference is the pump body, which incorporates a separator tank and non-return valve to enable self-priming operation.
All product wetted parts are manufactured from AISI 316L stainless steel. Other stainless steel components are produced from AISI 304. Internal surface finishes achieve bright polish values of Ra below 0.8 microns, supporting hygienic operation and effective cleaning.
The motor complies with IEC standards and is protected by a stainless steel shroud. Height-adjustable hygienic legs are supplied as standard.
The PROLAC HCP SP pump is supplied with an internal balanced single mechanical seal of hygienic design. The rotary seal face is manufactured from silicon carbide, with a carbon stationary face and EPDM elastomers.
Alternative seal materials and double mechanical seal arrangements are available to suit specific process requirements.
The pump is fully compatible with CIP and SIP procedures within the specified temperature limits.
The PROLAC HCP SP pump can be configured with a range of options, including alternative hygienic connection types, SiC or SiC double mechanical seals, FPM gaskets, motors with different voltages or protection classes, and motors suitable for explosive atmospheres or enhanced safety requirements.

What is the PROLAC HCP SP pump used for
The PROLAC HCP SP pump is primarily used for CIP return duties and for pumping hygienic liquids that contain air or gas without losing pumping capacity.
How does the self-priming function work
The pump separates air from liquid using an integrated separator tank, allowing air to be discharged while liquid is recirculated back into the pump until normal centrifugal operation is achieved.
Does the PROLAC HCP SP require a vacuum pump
No. The self-priming design removes the need for vacuum pumps, foot valves or additional priming equipment.
Is the PROLAC HCP SP suitable for CIP and SIP systems
Yes. The pump is designed for hygienic service and supports CIP and SIP cleaning procedures within the stated temperature limits.
What UK support is available
Pumps and Gearboxes provides UK based technical support, spare parts supply and service assistance for the INOXPA PROLAC HCP SP pump range.
