Choosing the Right Pump for the Job

PlaceHolder (2)

At Masterflow, we understand the complexities of HVAC systems and the importance of delivering the right solution. Using the extensive knowledge and experience of our senior engineers and highly qualified technicians, we’ve made it our business to supply only the highest-quality HVAC systems and components; this includes multi-function chillers & heat pumps, buffer tanks, expansion vessels, and of course, pumps.

In last month’s blog, we discussed the difference between four-pipe and two-pipe chillers. In this blog, we’re going to focus on pumps. We’ll be looking at seven different types of pumps, weighing the relative merits of each, and identifying the applications to which each pump is best suited.

Circulator Pumps 

Circular pumps are used to circulate liquids within a closed circuit. These compact pumps are often used to circulate heating water where there is minimal flow rate and head pressure. They are a perfect solution where space is limited, and they can be mounted on a wall out of the way. The relatively simple design of circulator pumps makes them easy to maintain, and a good quality circulator should last years without the need for any maintenance or repairs.

Vertical Inline Pumps 

These are another good option where a pump is required for a restricted space, with a footprint that is up to 30% smaller than traditional horizontal end suction pumps. The Bakerline vertical inline pumps offered by Masterflow are designed for maximum efficiency and long-term serviceability.

Sea- and River Water Pumps 

Specially designed to handle corrosive liquids like sea water and river water, these centrifugal pumps are most often used for Harbour Water Heat Exchange / Condenser Water / Heat rejection systems. The Bakerflow SWD range of pumps from Masterflow feature a casing material of 2205 stainless steel or Super Duplex Stainless steel and are capable of generating flows of up to 500 litres per second.

High Pressure Pumps 

High pressure pumps of up to 40bar may be suitable for applications where there is a need to generate or withstand significant head height, as is often the case with high-rise buildings. Among the high pressure pumps offered by Masterflow, we have the BakerFlow and Baker Bloc series. BakerFlow pumps can generate flow rates of up to 300 litres per second, making them ideal for many heavy-duty systems.

Closed Coupled Pumps 

A closed coupled pump is a variation of the centrifugal pump that is designed to remove the complications associated with separate couplings, eliminating the need for intricate alignment operations once the pump is mounted. The Baker Bloc closed coupled pumps sold by Masterflow offer an economical and space-efficient alternative to conventional centrifugal pumps.

Multistage Pumps 

Our selection of multistage inline pumps condense the best parts of a traditional motor pump into a compact, in-line design. Made from 304 or 316 stainless steel, these multistage pumps can handle a variety of liquids and are often used in run around coils, as well as in primary and secondary loops in heating water circuits.

Long Coupled Pumps

Long coupled pumps are designed to be paired with electric motors and diesel engines, and they can provide long service with very little maintenance. The Baker SW series of long coupled pumps are made with bronze and stainless-steel impellers, and they are best suited to use in heavy industries.
