PUK VARI COM - Commercial Booster Pump

Being a commercial grade mains water booster pump the PUK VARI COM is capable of a wide range of duties and can be tailored to offer the highest efficiency and produce energy savings over old pumps while exceeding the current requirements.

• PUK VARI COM SM (2 or 3 Pump) – 2.2 to 4.4 l/s Flow & 1-12 bar Pressure
• PUK VARI COM MD (2 or 3 Pump) – 2.6 to 7.2 l/s Flow & 1-12 bar Pressure
• PUK VARI COM LG (2 or 3 Pump) – 6 to 12 l/s Flow & 1-12 bar Pressure
• PUK VARI COM XL (2 or 3 Pump) – 9 to 18 l/s Flow & 1-12 bar Pressure

Pumps with a higher specification (duty or flow) can be built to order, please contact our team to discuss. For a pump with less performance please see the PUK VARI BOOST and PUK VARI TWIN.

When our PUK VARI COM units are first turned on the control panel initiates our unique ‘Safety Fill’ feature to protect from rapid pressurisation. In tall buildings when a booster pump is first started, water can fill the system rapidly and create a hydraulic shock surge also known as ‘water hammer’, which can cause extreme damage to the pipework.

The only pump that has this system is the PUK VARI COM. If you would like to discuss this feature in regards to your specific building then please contact our booster pump team at boosters@pumpsukltd.co.uk.

We only use the highest quality variable speed inverters in our booster sets to provide the easiest operation/maintenance and the highest efficiency. Using precise transducer pressure measurement the inverters adjusts the pump performance to provide consistent water pressure as the building water demand increases/decreases. This highly efficient control offers great energy savings over old fixed speed systems and removes the risks of sudden pressure problems in the buildings pipework.

• Built-In LCD Display (Status Notifications & Alarm Notifications)
• Low-pressure threshold settings (to cut out if low water switch fails)
• Switch loads across pumps to ensure equal load/wear
• Reliable Danfoss Transducer Pressure Sensor
• Nastec NOW App Programming (iOS or Android)

The PUK VARI COM is can be built using a selection of pumps, most commonly Lowara SV range and Ebara EVMS ranges of vertical multistage boosters. The ability to select between this huge lineup of pumps allow us to customised the PUK VARI COM to suit your exact flow and head requirements.

• Stainless Steel Construction
• Robust and Reliable Design
• WRAS Approved Pumps
• Suitable for Potable Water

Our PUK control panels are completely pre-wired into the inverters allowing simple control from the one panel allowing you to enable/disable the system with ease.

Our panels are fitted with a unique ‘Slow Fill’ function that only starts only one pump first when the power is switched on to the set. The pump will then pre-fill the vertical riser dramatically reducing the risk of hydraulic shock damaging the pipework system when the pump is fully started. This is unique Pumps UK technology and not available elsewhere.

The panel itself is quite complicated and you can see that as soon as you open the door but the outside has been kept simple for ease of use. There are two large lights, a power supply indicator and an error indicator alerting you to call our engineers. You can also turn each pump off at the turn of a switch and there is a switch to turn the pump off completely.

• ‘Safety Fill’ Startup Mode
