The APV W+ pump series is based on a unique hydraulic design that ensures maximum efficiency, allows for the highest hygienic standards and reduces noise and vibration. The W+ range consists of 16 standard models with pressure and flow capacities to 217psi and up to 1,760gpm. A number of special versions are available, including the Wi+ inducer pump for low NPSH applications and the Ws+ self priming unit designed to handle CIP return and other fluids with entrained air and foam.

The APV model V² centrifugal pump is a simplified and maintenance-friendly pump featuring a four-blade, fully open, non-clog impeller. Enginneered for CIP cleaning, and offering a choice of five seal types, the V² pump meets 3-A sanitary standards and is suitable for applications in the food, dairy, beverage, brewing, bakery, meat, pharmaceutical and chemical industries. The back plate is machined from heavy 316 stainless steel plate; the casing has controlled wall thickness and dimensional accuracy throughout; and a clamping assembly uses investment cast clamp rings with a self-locking internal angle for optimum sealing between casing and back plate. The V² pump is available in eight sizes with capacities to 500 US GPM and heads to 300 feet. Specialty models include pedestal mount, portable bases, and complete hopper assemblies.

Environmental requirements are getting strict. 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. Wa+ pumps ensure absolutely aseptic production processes with barrier media up to 150°C (320°F). With a Wa+ pump, the risk of contaminating the product and environment is thus reduced to an absolute minimum.

The Whp+ series pumps are designed to withstand system pressures up to 870 psi (60 bar) such as those in certain reverse osmosis systems. The Whp+ pump's sturdy construction increases stability and dampens vibrations.

The inducer pump is the alternative to changing the process design when NPSH availability is low. The inducer boosts the inlet pressure, and the risk of cavitation is correspondingly reduced (the NPSH required typically drops by 50-70%). When the risk of cavitation disappears, so does the risk of a large number of operational disturbances that would otherwise result - such as excessive noise, energy loss, product damage and unnecessary wear on the pump. Low suction head is a common "problem" in miscellaneous applications, e.g. when pumping products with low boiling points or in processes that involve vacuums.

The self-priming Ws+ is designed to handle Clean In Place (CIP) return and other fluids with entrained air and foam. The unique design reduces the energy consumption and noise of traditional liquid ring pumps by using a high efficiency impeller that can be trimmed to match a specific duty. The Ws+ employs a built in eccentric air screw to form the liquid ring required for its self-priming capability.
