North Ridge RLP Rotary Lobe Pumps For Viscous and Sensitive

RLP Rotary Lobe PumpsOverview Our industrial and sanitary rotary lobe pumps are highly reliable and efficient designed for the handling of low to high viscosity fluids which are either clean or have concentrated solids in suspension. Due to their high efficiency, low shear pumping motion and cleaning in place characteristics, these units are typically used for the transfer of sensitive and hygienic fluids within the biotechnology, pharmaceutical, chemical, food & beverage markets. Their rotary positive displacement operation ensures a smooth non-pulsating flow of media, enabling them to be used reliably with flowmeters and ensure that mixtures remain unchanged by pumping motion. The design of our RLP Rotary Lobe Pump allows not only the pumping of thin liquids, but also mixtures containing large suspended and concentrated solid particles such as olives, molasses, syrups, fruits and vegetables. The internal casing is designed to accommodate easy CIP cleaning through the addition of a flushing line connected directly to the seal, guaranteeing seal faces remain clean when handling sticky, abrasive mixtures. Designs are available with either a heating or cooling jacket for the maintaining of pumped fluid temperature, safeguarding sensitive liquids ensuring they remain within set temperatures for the preservation of hygiene. This range is designed with the ability to run dry for long periods of time without damage to the internal lobes or seals as the seal is located within an oil bath. The internal design has been optimised over many years to improve efficiency, ensuring clearances remain tight, that there is close to zero slip, reducing power consumption confirming their suitability for continuous operation. Applications Some of the most common fluids our rotary lobe pumps are used for include chocolate, molasses, pulp, creams, syrups, lotions, purees and greases. Our units are manufactured according to UKCA and CE standards complying with both UK and European regulations. Certification Our rotary lobe pumps are also available with ATEX (explosion proof) motors for hazardous environments, and can be supplied with a variety of seal types such as mechanical seal, cartridge seal, packing seal and lip seals to accommodate almost any fluid pumped.
