How to increase your efficiency with our UK built chemical pumps

2018-12-14T07:03:05+00:00 August 24th, 2018|

When selecting larger pumps for capacities over 100m3/hr there are many factors to take into consideration to ensure that you have the most efficient option. With an anticipated life of several years it is obviously important to choose a pump that operates at, or very close to, its BEP which can result in significant savings [...]

The Flexible Design of Vertical Pumps

2018-12-14T07:03:15+00:00 August 2nd, 2018|

Crest Pumps has the ability to supply specialist pumps at competitive prices on short lead times. This is particularly true of its range of vertical pumps which can be easily adapted to fit into customers’ installation constraints without compromising efficiency or delivery time. James Dashwood, MD of Crest Pumps, says “A typical example is when one [...]

How does a Magnetic Drive Pump Work?

2018-12-14T07:03:33+00:00 May 9th, 2018|

Magnetic drive pumps have been available for many years and are ideal for use with clean liquids, their obvious advantage in chemical applications is that they eliminate the need for potentially expensive mechanical seals. Magnetic drive refers to the coupling between the motor and the impeller. In traditionally sealed centrifugal pumps the impeller is driven [...]

What is The Difference Between Submersible and Immersible Pumps?

2018-12-14T07:04:59+00:00 May 9th, 2018|

These terms can often be confused though the distinction is fairly obvious. Submersible pumps are complete units, including the motor, and the whole can be totally submerged whereas immersible pumps are mounted in vertical position with the motor above the liquid and the pump end extended below the liquid level. Submersible & Immersible Pump [...]

What is a centrifugal pump and how do they work?

2018-12-14T07:05:08+00:00 April 30th, 2018|

What is a centrifugal pump and how do they work? A centrifugal pump is essentially quite a simple machine. An impeller rotates at speed within a casing so creating a centrifugal force on the liquid which is discharged through a port on the periphery of the casing, it follows that the faster the impeller rotates [...]

Plastic Pumps and their use in Industry

2018-12-14T07:05:17+00:00 April 26th, 2018|

Plastic Pumps Use in Industry - Thermoset plastics have been used in making pumps and pipelines for well over 50 years. Traditionally when faced with selecting pumps for handling corrosive liquids engineers were faced with using pumps made from high nickel content alloys such as Hastelloy or using pumps lined with ceramic or glass. The [...]
