The PUK VARI COM cold water booster set has been designed as a cost-effective solution for commercial applications such as hotels, offices and large residential properties. This booster pump is fully WRAS approved ready for use with potable water.

The PUK VARI COM is built using high-quality pumps and components with a common control panel and motor mounted inverters. Each unit has a pressure vessel included with a flow-through valve and a drain cock for easy maintenance.

We can also supply the PUK VARI COM anti-vibration mounts, flexible connectors and cut out float switches. Call 01322 292 415 to discuss your requirements.

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.

The units also have a “Safety Fill” function that only starts one pump when the power is switched on to the set. The pump will only fill to a pressure equal to that of the riser. Reducing the risk of hydraulic shock damaging the pipework system.

• Heads up to to 10 bar (100m)
• Flow up to 18 l/s (64.8 m3h)

The units are controlled to give a constant pressure and will ramp up speed when the demand increases in the building. This type of control will give clients savings on energy and reduce the risks of pressure problems in the systems pipework.

• Built-In LCD Display
  • Status Notifications
  • Alarm Notifications
• Low pressure threshold settings (to cut out if low water switch fails)
• Automatic switching between pumps to ensure equal load/wear
• Bluetooth Setup/Monitoring using Nastec Now App (iOS/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 BOOST to suit your exact flow and head requirements and ensure sully and reduce construction times.

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

Our PUK control panels are completely wired into to the inverters allowing simple control from the one panel.

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.

• Individual Pump Isolators
• Low Water Cut Out Connections
• Common Volt Free Fault Contact
• Upgradable for full BMS control + MODBUS or BACnet protocols
