Smaller pumps displace more fluid
The DW range of rotary lobe pumps is designed for economical operation and careful handling of high-viscosity or delicate products.
In common with all APV's high quality product range, the DW pump is designed for economical operation.
Due to an improvement in hydraulic performance, it is possible to run the DW 6 and 7 at up to 800rev/min.
The combination of the size and speed means that the DW 6 and 7 are among the highest capacity positive displacement pumps.
The DW 6 and 7 pumps are an extension of the DW 1-5 range and include the same unique features, including an increased inlet behind the rotors, resulting in a low NPSH requirement, decreased noise at high speed, and minimum local cavitation, due to its specially patented rotor tips and grooves.
The DW 6 and 7 piston versions run without pulsation when handling viscous products.
Whereas the minimum pulsation design of the bilobe makes it suitable for high pressure/flow applications.
The DW 6 and 7 are specially designed for large-scale hygienic applications within the dairy industry, pumping whey and curd within the production of cheese.
They are also used to pump juice and have applications in the brewery industry.
The DW 6 and 7 were officially launched in June 2002, and are already proving popular, with particular interest from customers in the cheese industry.
The pump is certified to meet EHEDG and 3A sanitary standards and with all seal materials in accordance with FDA approval.
These new pumps reflect the excellent quality for which APV products are renowned.
