Compact plunger pump with a big performance

Posted: Monday 14th September 2009

Cat Pumps UK Limited has expanded its range drive triplex plunger pumps.

Conceived as a competitively-priced multi-application compact pump for the OEM sector, the new 7CP product line offers designers and users all the quality, performance and build attributes traditionally associated with Cat Pumps. The valves and seats are manufactured from 304 Stainless Steel and are hardened and polished for ultimate seating and extended life. The forged brass manifold provides high levels of strength and resistance to corrosion, and the V-packings that are lubricated and cooled by the pumped fluid run on highly-polished alumina ceramic plungers resulting in excellent service life.

The ‘press-in’ style seal case and convenient access to the inlet and outlet valves makes the pump easy to maintain and operate.

Capable of pressures between 7 and 140 bar and flows up to 41 l/min, this positive-displacement pump is remarkably compact, delivering a performance that previously would have required stepping up to the next largest pump in the Cat Pumps product range. The 7CP products can be direct-driven at 4-pole or 6-pole motor speeds using a Cat Pumps bell-housing mounted directly to a suitable B5 motor flange. As a result, the 7CP plunger pump can fulfil those duties on plant and equipment where space is at a premium. Equally, should an intermediate speed be required, the 7CP pumps can be installed on a base plate using dedicated mounting rails, complete with belt-drive or inline geared motor.

According to Cat Pumps, the applications for their 7CP range are too numerous to mention. However, in those countries where the pump has already been introduced, popular applications include stationary in-plant cleaning units, vehicle cleaning, misting, multi-lance wash down units in the food industry and coolant flushing.

A full range of installation accessories is available to complement this new development from the most highly regarded manufacturer of high-pressure pumps of this type. Data sheets on all these products, together with comprehensive application and installation guides, are available for download from
