Process pump gains 20% power increase

LEWA GmbH, a specialist in advanced diaphragm pumps, has improved the performance of its LEWA ecoflow LDH Boxer process pump by 20%, enabling operators to increase efficiency.

The upgrade to the LEWA ecoflow LDH Boxer (LDHB) process pump enables users to boost performance without resizing equipment or incurring additional system costs. For example, at a flow rate of 2,200l/h, the maximum discharge pressure rises from 622 bar to 746 bar. Alternatively, at 75 bar, flow capacity increases from 18,000l/h to 21,600l/h.

Commenting on the update, Nicoline Walther, Product Manager for the LEWA ecoflow product range, said: “Optimising productivity in processing applications is a constant challenge. The boxer pump design is already very efficient, as one drive unit moves two pump heads. With the increase in performance, the LDHB provides twice as much hydraulic power compared to a single pump.”

This upgrade follows a 15% performance increase to the smaller LDG pump last year. The LDHB now extends these gains to higher-capacity applications with a 20% increase in hydraulic power from 38 kW to 46 kW.

The LEWA ecoflow range, a modular system of diaphragm and packed plunger metering pumps, combines numerous drive sizes and pump heads for high application flexibility. Multiple materials and valve type options mean ecoflow pumps are highly customisable and can be configured for demanding media, including aggressive, abrasive, or toxic fluids across energy, chemical and process industries.
