Calpeda GQV 50 & 65 Submersible Pump



Calpeda GQV 50 & 65 Submersible Pump

The Calpeda GQV 50 & 65 is the new submersible dirty water drainage pump that has recently been added to the GQV 50 Series, following the same logic and construction principles.

The new pump is more than a mere extension of the range. This drainage pump is, indeed, built to allow the management of suspended solids with a diameter of up to 65 mm, a feature that renders it particularly suitable for industrial applications.

Suspended solids treatment is an extremely important aspect of dirty waste water lifting. It is, in fact, essential that the pump be reliable and able to move the liquid without getting clogged. Think, for example, of applications such as those of sewage treatment plants run by municipal companies that must provide efficient service without downtime caused by breakdowns or clogging.

Therefore, we may say that with the GQV 65 pumps, Calpeda has ushered in, among its products, a new line destined to grow further, namely that of the dirty water drainage pumps for the industrial sector.

Moreover, if we consider the market offer for this type of product, the GQV 65 pump positions itself by means of its specificity which differentiates it from most of the available devices.

It is, indeed, a pump characterized by excellent value for money, equipped with a high-performance motor with a stainless-steel casing, much lighter than the ones in cast iron, typically used in pumps designed for this type of application.

As for the construction features, here are some of the main aspects that highlight the excellent hydraulics and the careful mechanical design of the GQV 65 pump.

•The pump is equipped with a vortex impeller, already by itself a guarantee of optimal performance for dirty water. The vortex impeller, in fact, is designed so that the solid particles pass below the impeller itself, which prevents its blocking.

• The presence of the vent valve allows the escape of air around the impeller and therefore is a guarantee of excellent priming even after extended periods of idleness.

• The pump is equipped with a double mechanical seal on a stainless-steel shaft with an oil chamber interposed for the safe protection of both the engine and against accidental dry running.

• For flexible and quick installation in the sump, the pump has a DN 65 delivery flange and a G 2 ½ thread as well; it is also suitable for coupling chutes.

The pump is currently available in 1.1 and 1.5kW power versions.

Thanks to the enlargement of the pump body, meant to allow the passage of suspended solids with a diameter of up to 65 mm, the GQV 65 pump guarantees, for the same power, a greater free passage and flow rate than the GQV 50 pumps.

Calpeda is a company that is committed to studying, developing, and manufacturing pumps and pumping systems. We want to continue that which was started many years ago by Vinicio Mettifogo, founder and pioneer.

It all began like this

Calpeda appeared on the British market over 40 years ago. At the start, the products were sold by two independent distributors, and then all the business operations in the United Kingdom were grouped into a single company, MSP Planet Limited, with its base in Bicester. In 1995 Calpeda SpA proposed the idea of starting a directly controlled company to Ken Hall and David White. The initiative, which led to the formation of the Calpeda Limited branch, became more solid with the purchase of MSP Planet Limited and the transfer of all staff to the new organisation.

Even Bigger

Year after year the subsidiary grew and sales development was gradually accompanied by the enlargement of the company headquarters. After a move to a new 20,000 sqft facility the plant was doubled in size with the acquisition of further buildings and an important restructuring program was initiated, at a cost of £ 1.5 million, which includes a new assembly and service area, new offices, and a training centre. Calpeda Limited also has a technical centre in Pontefract - West Yorkshire which has generically grown over the years. Markets in the Republic of Ireland and Northern Ireland, are serviced by a subsidiary of the UK operation called Calpeda Pumps Ireland Limited, with its headquarters in Dublin.

Our strong points: product quality assurance and trained staff

Calpeda Limited supplies a wide range of Calpeda products to many industrial and commercial sectors, through a capillary distribution network and business-to-business platforms. Calpeda Limited also features a flexible, well-equipped, and experienced booster set, pressurisation, and specialist pump system production centre, mainly for the building services sector. The company has a strong expansion program with the aim of increasing sales and has recently invested in an important part of this growth strategy, namely after-sales services. Service is one of the branch’s strong points, the company is naturally made up of highly skilled, specialist Engineers, and a training project providing development opportunities to young Engineers is long established.
