Available in 8 models, APV DW rotary lobe pump includes inlet that produces low Net Positive Suction Head (NPSH) requirement, decreased noise at high speed, and minimum internal cavitation. Rotor tips and grooves in piston rotor design allows pump to run without pulsations when handling viscous products. Able to handle delicate products, pump may be fitted with thermal jacket to heat or cool pump chamber prior to product entry.Original Press Release:
APV Upgrades DW Rotary Lobe Pump
New positive displacement pumps for the food, pharmaceutical, cosmetic and chemical industries are less costly to operate and have increased flow rates
LAKE MILLS, WISCONSIN, USA, September 19, 2002 -- APV, a leading provider of processing solutions and products for the food, beverage, pharmaceutical and healthcare industry, and a unit of Invensys plc, has announced eight new models of the popular selling DW rotary lobe pump with flow rates as high as 1,600 gpm.
Since its launch three years ago, the DW rotary lobe pump has proved highly successful for the careful handling of high-viscosity or delicate products. Thanks to an improvement in hydraulic performance, the new pumps are smaller and less costly to operate.
The APV DW pump includes a number of unique features such as an increased inlet behind the rotors that produces a low Net Positive Suction Head (NPSH) requirement, decreased noise at high speed, and minimum internal cavitation. In addition, specially patented rotor tips and grooves in the piston rotor design allow the pumps to run without pulsations when handling highly viscous products. This ensures the steady filling and discharge of the product, and extends the lifetime of valves and instrumentation.
The pump is frequently selected for its ability to successfully handle delicate products. Its gentle pumping action ensures minimum damage to particles. Equally important is its flexibility - thermal jackets can be fitted as an option to heat or cool the pump chamber prior to product entry. This prevents even minor temperature changes which can cause severe damage to sensitive products.
The APV DW pump is certified to meet European Hygienic Equipment Design Group (EHEDG) standards, 3A sanitary standards and FDA requirements for all seal materials. It is designed for easy maintenance and features a front loaded shaft seal. Irrespective of whether the pump is fitted with the standard single mechanical seal (Silicon Carbide/Carbon) or the optional flush version (Silicon Carbide/Silicone Carbide), all seals can easily be changed without having to disconnect the pump housing or pipework. It also features easy access to other key components such as the gearbox.
The pump's design makes it easy to clean and its pressure relief valve is totally CIP/SIP cleanable without special procedures.
The DW pump is also extremely versatile. It can be used as a CIP feed pump, eliminating the need for an additional pump and the associated plant routing. Its inlet / outlet orientation can be changed from vertical to horizontal in minutes, simply by disconnecting the feet. A single pump head is suitable for a pump in either configuration, reducing spares requirements.
