Product catalog summary
Introduction
SPX FLOW's APV products are engineered to adhere to international hygiene standards, emphasizing easy cleanability and resource efficiency. The product line includes pumps, valves, heat exchangers, mixers, and homogenizers for industries such as food, dairy, beverage, chemical, personal care, and pharmaceuticals.
Product Features and Benefits
The DW series pumps are characterized by high volumetric efficiency, ultra-hygienic design, pulse-free performance, low NPSH requirement, gentle product handling, easy maintenance, low noise levels, and compliance with global design standards. They can operate at high capacities, reaching up to 800 rpm and pumping up to 1,016 liters per 100 revolutions.
Theory of Operation
DW pumps are positive-displacement, low-slip, stainless steel pumps with larger diameter shafts for enhanced strength. They function by creating expanding cavities at the inlet to draw liquid into the rotors, which then mesh to expel the fluid.
Product Specifications
The DW pump range consists of 26 models with capacities ranging from 3 to 1,016 liters per 100 revolutions and pressures up to 30 bar. All contact parts are made from AISI 316L stainless steel, and elastomers meet FDA standards. The pumps offer interchangeable piston and bi-lobe rotors and flexible porting options.
Design Features
Options include rectangular inlets for high viscosity products, thermal jackets for temperature-sensitive products, and relief valves for pressure control. Rotor types such as Multi Duty, High Efficiency, NGA, and High Temperature are available, each tailored for specific applications and temperature ranges.
