1. Brief Introduction

Rotary Lobe pumps are used in a variety of industries including food, beverage, pharmaceutical, cosmetics, pulp and paper, coating and painting, oil and gas, daily chemical, and biotechnology. They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance and good clean-in-place and steam-in-place (CIP/SIP) characteristics.

Rotary lobe pumps can handle slurries, pastes, and a variety of liquids. If wetted, they offer self-priming performance. A gentle pumping action minimizes product degradation. They also offer continuous and intermittent reversible flows and can operate dry for brief periods of time. Flow is relatively independent of changes in process pressure, too, so output is relatively constant and continuous.

BV Series Lobe Pumps are self-priming, valveless, positive displacement pumps. The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.

2. Features

• Gap is kept between the rotors and between the rotor and the pump body, no friction,long life.
• Simple assembling and disassembling, easy to maintenance and clean, strong resistance to wearing.
• High efficiency and energy-saving, low failure rate, reliable sealing and low noise.
• Special materials are used to pump materials with soild granules, like sludge and sewage.
• Capable to pump the viscous materials up to 1.5 million cps and pulp with the solid volume of 60%.
• Equipped with frequency converter, flux can be adjusted at will and can be used to as general measurement pump.
• Flange, screw, or clamp connection can be used, as required by the customer.
• Capable of pumping mixtures of gas, fluid, and solid materials.
• Heating & cooling pumps is of built-in structure, with well heat conductivity.
• Movable pumps can be used to pump canned medium, with intake vacuum of 0.08 Mpa.
• Hygienic safety valves can be set at the pumps head if customer required.
