SPX APV W+

Applying the SPX APV centrifugal pump W+ Range

The SPX APV centrifugal pump W+ is characterized by problem free operation and a long life cycle. The pump design is particularly robust with a new hard wearing shaft seal and an extension frame of stainless steel as standard.

Operating reliability has been thoroughly tested. Every pump is tested individually in a computer-controlled test bench. A test certificate is provided with each pump. All W+ pumps are designed for system pressures up to 14, 18 or 25 bar – as standard.

Complete product range

The SPX APV centrifugal pump W+ range consists of 17 standard models with pressure and flow capacities up to 15 bar (50 Hz) and up to 800 m³/h (50 Hz). There are a number of special versions, which may be adapted specifically to customer requirements. As the W+ pumps are modular, customized versions can be provided to undertake specific pumping duties. The name of the pump refers to its best efficiency point (BEP). W+ 22/20 for example, attains its BEP when the differential pressure is 22 mWc and the flow capacity 20 m³/h (50 Hz). All pumps operate at 50 Hz and 60 Hz.

Motors

To meet global demand, W+ pumps are supplied with either IEC or NEMA standard motors.

W+ multistage pump

The W+ 140/50 offers three special features:

  • Provides pressures up to 15 bar
  • Can be used in processes with system pressures up to 60 bar
  • Ensures optimum hygienic standards

Unlike other multistage pumps, the W+ is CIP friendly. It has open impellers and semi-open impeller vanes eliminating any hiding place for bacteria. The W+ multistage pump is equipped with heavy duty bearing bracket that absorbs all radial and axial forces present in pumps of this kind. Therefore the W+140/50 can use standard motors of any make.

Whp+

The Whp+ is a high-pressure model of the W+ range. These pumps are designed to withstand system pressures up to 870psi (60 bar) - such as those in certain reverse osmosis systems. The Whp+ pump’s sturdy construction increases stability and dampens vibrations.

Wa+

Unfortunately environmental requirements are getting stricter and stricter. But today, aseptic production is already essential to certain processes - including the manufacture of long life food and pharmaceutical products. The Wa+ pump is the perfect solution. All seals, including the shaft seal, are designed as double seals.

  • Double mechanical shaft seals fitted for sterile flushing
  • Double O-ring sealing of pump housing fitted for sterile flushing
  • Special aseptic fittings fitted for sterile flushing
