Introducing Side Channel Pumps

Our side channel pumps are designed for applications that standard end suction centrifugal pumps cannot handle. The main benefits include: Low NPSH – Can operate with as little as 0.35m Low Flow – Ideally suited to low flow applications, as low as 0.4 m3/hr High Pressure – 8-9x higher pressure…

Our side channel pumps are designed for applications that standard end suction centrifugal pumps cannot handle. The main benefits include:

    • Low NPSH – Can operate with as little as 0.35m
    • Low Flow – Ideally suited to low flow applications, as low as 0.4 m3/hr
    • High Pressure – 8-9x higher pressure can be achieved compared to a centrifugal pump (up to 40 bar)
    • Gas Entrained Liquids – Having gas entrained in a liquid is no problem, our side channel pumps can operate with up to 50% entrained gas
    • Suction Lift – Self-priming suction lift of up to 8.5m
    • Easy Controllability – Due to the steep curves that these pumps operate on we can easily control head and flow
    • Low Viscosity – These pumps can also handle lower viscosity compared to most pumps in the market today
    • Extreme Temperature – As standard, these pumps will operate at between -20° → 120°, with an upgrade we can achieve -60° → 220°

With the above advantages we can also supply mechanical seal systems, magnetically driven systems and even canned motor systems. Due to the modular design we can have over 4800 mechanical variants which helps us become extremely flexible to your system requirements.

Standard materials can be cast iron, duct iron, bronze, stainless steel and chrome steel.

Applications include:

Refrigeration | Condensate Recovery | Ad-Blue Filling | Gasoline blending | Gas entrained liquid applications
Selective catalyst reduction | Butane applications |Fuel from underground tanks | Automotive filling stations

Enhancing Control and Safety in Tanker Unloading Operations

A long-term customer, who operates within the chemical manufacturing industry, approached us because they needed to modernise and improve control over their tanker unloading processes. Their existing systems operated by either using the “blowing method” or relying on pumps mounted on the tankers and weren’t particularly reliable, consistent, or safe, especially when it comes to handling aggressive chemicals such as 96% Sulphuric Acid and 50% Hydrogen Peroxide.

The Right Pump for Fume Scrubbers

Chemical pumps improve the performance of your fume scrubbers! 
It’s a bold statement, but true.  Industrial ventilation plays a key role in workplace safety and regulatory compliance in manufacturing plants. Industries like chemical processing, pharmaceutical manufacturing, and metalworking rely on robust (and reliable) ventilation systems to remove harmful fumes, particulates,…

Our Guide to Distillery Pumps

What You Need to Know
Moving thousands of litres of valuable spirits through various production stages each day, pumps are at the core of alcohol manufacturing and distilleries. A single pump failure can completely stop production, compromise product quality, and result in significant financial losses for UK distillery operations.
Choosing the right…
