Engineered for High Pressure, Strength and Sanitary Performance

Designed to perform under pressure, the APV® WHP+ pump’s features a reinforced construction that enhances mechanical stability and reduces vibration, ensuring reliable operation and extended service life. Engineered to meet the strictest global standards, it complies with EHEDG-certified and 3-A design requirements for sanitary processing applications with certificates available for high-running versions.

The WHP+ is ideal for reverse osmosis systems, evaporators, and high-pressure feed duties, offering gentle, non-pulsating flow that protects product integrity while maintaining efficiency and safety.

Thanks to its modular design, the W+ platform enables engineers to configure a perfectly tailored pump for hygienic processing duty — ensuring optimal efficiency, cleanability and reliability across a wide range of sanitary and industrial applications.

Why Choose the APV Whp+ High-Pressure Centrifugal Pump

• Robust Stainless-Steel Design: Increases stability, reduces vibration, and enhances durability.
• Hygienic Construction: Complies with EHEDG-certified and 3-A design requirements for sanitary processing applications.
• Energy-Efficient Hydraulics: Optimized impeller and volute geometry for superior flow with lower energy use.
• Easy Maintenance: Modular design and standard seals simplify servicing and reduce downtime.
• W+ Series Compatibility: Shares components with the W+ platform, reducing spare part requirements and simplifying integration.

Maintain Flow Stability and Reduce Energy Use

Traditional sanitary pumps can struggle to maintain stable, efficient performance under high pressure — leading to vibration, excess energy consumption and reduced equipment life.

The APV WHP+ Series overcomes these challenges with a sturdy, precision-balanced design that minimizes vibration and mechanical stress. This stability ensures consistent, energy-efficient operation, even in continuous high-pressure environments such as reverse osmosis or nanofiltration systems.

Consistent Performance in High-Pressure Environments

As an extension of the W+ Series, the WHP+ brings proven reliability to high-pressure sanitary processing. It delivers the pressure stability and cleanability required in applications like reverse osmosis, evaporation and product concentration, while maintaining the gentle, non-pulsating flow that preserves product characteristics.

Theory of Operation

The WHP+ operates using the centrifugal pump principle. Fluid enters through the eye of the impeller, where rotational energy increases its velocity and pressure. The volute casing then converts this velocity into pressure energy, generating a steady, high-pressure discharge.

Optimized internal geometry ensures smooth, non-pulsating flow, while the reinforced casing maintains performance under differential pressures typical of RO, UF, and NF systems. The result is efficient, reliable liquid transfer that minimizes cavitation and energy loss.

Committed to Sustainable, Energy-Efficient Performance

The WHP+ supports sustainability by combining energy-efficient design with durable construction for reduced environmental impact and long-term operational value:

• Lower Energy Consumption: Streamlined hydraulics minimize power use.
• Extended Service Life: Vibration control reduces wear on components.
• Resource Efficiency: CIP/SIP compatibility reduces cleaning water and chemical demand.
• System Integration: Works within our process lines to improve overall energy efficiency and reduce carbon footprint.
