Competitive pump introduced to hygienic sector
19 June 2007
The Mono brand has introduced Helios, which is a new range of progressing cavity (PC) pumps for the hygienic market. Mono are optimistic that its polished stainless steel construction will appeal to end-users and OEMs in the food, dairy, beverage and pharmaceutical sectors.
The twenty-nine models in the Helios range feature a compact design with a one-piece suction chamber that is easily cleaned and has no areas where product could collect, reducing the risk of contamination. From a practical standpoint, the pump can also be dismantled without removing the drive, which makes inspection and maintenance easier and reduces the risk of damage to the mechanical seal, whilst working on the pump.
The range handles flow rates up to 180m3/h and pressures up to 24 bar. Polished stainless steel is used for all metal parts in contact with the product and reliable operation and reduced downtime is further ensured by the inclusion of a sealed pin joint. Inlet and outlet fittings are threaded as standard to DIN 11851, with alternatives available on request. White stators can also be specified as well as a full range of industry related options, including CIP bypass connection ports.
The arrival of the Helios range makes PC pumps an increasingly viable option in the hygienic market. Mono anticipates that they will now be viewed as a practical alternative to lobe pumps. For example, Helios exhibits better seal and wear characteristics; minimal reduction in flow; gentle handling of shear sensitive products at high flow rates; inherent self-priming; minor slippage with low viscosity fluids; and lower service costs due to employment of single shaft and seal.
Commenting on the news, Mono Marketing Manager, Nichola Vasconcellos said, “The design of Helios has enabled Mono to offer a range of pumps at a competitive price for the hygienic market without compromising performance. The name – with its connotations of the sun – should make it a memorable one for the hygienic sector. It also puts people in mind of the word helix and so reconnects with the shape of the rotor which is at the heart of every PC pump.”
