Flexible Impeller Pumps are a type of positive displacement pump, their impeller’s vanes maintain constant contact with the pumps inner walls whilst rotating, causing a vacuum which pushes the fluid through the pump.
They are available in hygienic and non hygienic, making them suitable for a wide range of applications, including the food & beverage industry, pharmaceutical, cosmetic, industry, marine, farming, and many more.
Most flexible impeller pumps provide a smooth, low pulsating flow with low shear operation, as their impellers are made from rubber, they are able to handle viscous fluids and fluids with high solid content without causing damage.
If you’re unsure of the right pump for your application, please contact us.
Peripheral pumps, also referred to as regenerative pumps, are centrifugal pumps whose impeller rotates in a largely concentric casing channel with an inlet and an outlet opening. The fluid in a peripheral pump is pumped into a peripheral channel (around the edge of the casing).
Unlike standard centrifugal pumps, the curves do not flatten as the fluid flow decreases. To summarise the fluid moves along the circumference for the inlet to the outlet of the casing with increasing pressure. Peripheral pumps are suitable for pumping uncontaminated liquids, e. g. as boiler feed pumps for small boilers, as pressure boosting pumps, car wash pumps, as pumps for the chemical industry and for all applications in which low flow rates have to be pumped at high pressure.
Multistage pumps are pumps with two or more impellers that are stacked on the same shaft and driven by the same motor. The flow will stay the same regardless of how many impellers a pump has, however each impeller boosts the pressure of the water, so the more impellers, the greater the pressure discharged. By having multiple smaller impellers, it makes Multistage Pumps more energy efficient than having one large impeller.
The main application for multistage pumps is water pressure boosting, but they are also used for borehole pumps, boiler feed pumps, irrigation and wash down facilities, plus many more.

Dosing Pumps, which are positive displacement pumps, are designed to inject (dose) a substance into a flow of water, gas, or steam, allowing the user to ensure accurate, linear and repeatable metering across all process conditions.
Dosing pumps can be used when it is necessary to add chemical treatments to water supplies, such applications include aquariums, swimming pools, marine use, industrial process or wastewater treatment, plus many more applications.

Engine driven pumps are very popular on construction sites, agricultural environments and in the marine industry. They are great for draining or moving large areas of water in remote areas, they usually have the highest flow rate available for pumps and are useful for when there is no electrical source available.
It is important to choose the correct pump for your application, dependant on what liquids are being pumped; if you are unsure on which pump to choose please contact us for help.
A circulator pump (or circulating pump) is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential energy to a point of higher potential energy).
Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps. As used in homes, they are often small, sealed, and rated at a fraction of a horsepower, but in commercial applications they range in size up to many horsepower and the electric motor is usually separated from the pump body by some form of mechanical coupling.
