SPX APV DW

Ultra-Hygienic, Accommodates Harsh CIP-Cycles

All SPX APV Rotary Lobe Pump DW models are CIP/SIP cleanable. The pumps are designed to withstand rapid temperature changes and can therefore accommodate very harsh CIP- cycles.

Pulse-Free Performance

When pumping highly viscous products, the DW pump with piston rotors runs completely pulse-free. This ensures a consistent process flow, which is required in connection with filling machines. It also safeguards valves and other equipment that can be damaged by pressure surges.

Low NPSH-Requirement

The highly improved suction capability of the DW pump considerably reduces the NPSH-requirement. This in combination with the absence of pressure pulsations makes the DW pumps ideal for many applications, such as ultra filtration.

Gentle Product Handling

The available rotor designs ensure maximum product integrity and minimize the risk of potential damage to sensitive products. Both piston and bi-lobe rotors are suitable for high and low viscosities. They can handle products as cheese curds and whey, soft fruit and meat — which previously required fitting special rotors.

Easy Maintenance

The easy-to-access, front loaded mechanical seals reduce maintenance time considerably. All shaft seal O-rings are identical and the access to the shaft seal is achieved by simply removing the front cover and the rotors. Likewise, the timing of rotors is an equally uncomplicated operation.

Low Noise Levels

The patented rotor design practically eliminates hydraulic noise and the helical gears minimize gearbox noise.

Global Design

The entire range complies with the European EHEDG and the American 3-A hygiene standards.

High Capacity

The DW6 high capacity pumps are unique in the field of positive displacement pumps. They are capable of running up to 800 rpm and pumping up to 1,016 liters/100 revs (268 gal/100 revs), approximately 370  m³/h (1,628 gal/min).
