New glanded pump has high efficiency

Wilo introduces a range of single and double-headed glanded cast-iron pumps designed to provide high levels of operating efficiency along with low operating costs for water-based pumping duties

Wilo has introduced a new range of single and double-headed glanded pumps specifically designed to provide high levels of operating efficiency along with low operating costs.

The new Wilo-BL, DL and IL pumps feature force-protected, bi-directional mechanical seals, IEC-standard motors and IP55 ratings for humid environments.

Suitable for handling hot and cold water in heating systems or mechanical services applications, these new glanded pumps are extremely versatile, as well as being tough, durable and efficient.

With a cast-iron pump body, impeller and lantern, the BL, DL and IL pumps are equally suited for water supply and irrigation requirements, condenser water systems and a host of other water-based pumping duties.

The new pumps have been specially constructed to exceed typical pump performance expectations.

For instance, the new range features maintenance-free, bi-directional mechanical seals, suitable for handling clean water at temperatures up to 1400C and for water/glycol mixtures to a minimum temperature of -100C.

The new single-stage, low-pressure centrifugal pumps utilise a standard totally enclosed, fan-ventilated, IEC standard electric motor - with worldwide availability - and a pump body constructed for working up to a maximum pressure of 16 bar.

These features ensure a long, hassle-free working life, with minimum maintenance requirements.

Mark Sowden, Marketing Manager at Wilo, explained the rationale behind the design of the new pumps.

"We've combined robust, cast-iron housings with an efficient centrifugal design and IEC motor.

The result is a series of cost-effective pumps that offer lower operating costs and reliable fluid transfer under a broad range of operating conditions.

With many of our customers focussing on life cycle costs we know that the increased efficiency that this new range offers will enhance still further our green credentials".

The Wilo-BL end-suction pump meets EN 733 and features a cast-iron volute with end-suction and radial discharge ports.

Both the Wilo-IL and Wilo-DL are of in-line design with the Wilo-DL featuring a flap valve to prevent re-circulation within the pump housing.
