DESCRIPTION

North Ridge NP3 Three Pump Booster Set



Flow Rate

Up to 36m³/hr

Head (Pressure)

Up to 90m

Drive Options

Electric Motor



Our three pump booster sets increase and supply constant pressure for cold water installations where pressure provided by the mains supply or feed tank is insufficient. Example installations include; domestic properties, commercial buildings, hotels, hostels, agriculture, district heating, nursing homes, laboratories, leisure parks and marine vessels.

 

The pumps can be constructed from either stainless steel 304 or 316 and are fully WRAS approved. They can be supplied in either horizontal or vertical configuration, either option is compact. Our booster sets come complete with pumps, powder coated baseplate, manifolds, valves, fittings, gauges, inverter drives and pressure vessels. Other bespoke pump sets with up to 6 pumps and other accessories are available on request.

 

The variable speed drives allow for full control of flow rate and pressure. They vary the motor speed of each pump depending on system requirements at any given time, while still maintaining a constant system pressure. By reducing or increasing the motor speeds to match the system requirements, significant power and cost can be saved. This is since the pumps only produces the required flow rate and pressure at that point in time, rather than constantly running at full capacity.

 

The frequency drive is mounted on the discharge pipework and comes complete with LCD display to provide the operator with information on the system parameters. The pumps can be operated in duty, assist or standby modes, they are programmed to run in staged cascade mode as pressure and flow rate demands increase.

 

Details on the inverter drive are below:

 

·         Temperature range of 0 – 60°C

·         Protection features, including; dry run protection, over current protection and over temperature protection

·         Changeover of duty pump automatically

·         Facility to wire a low-level float switch

·         Volt free contacts to allow for remote alarm

FAQS

In order to select the correct sized cold-water booster set, we need a detailed description of the installation. Ideally, we would like you to tell us the exact flow rate and pressure required from the pumps. If you don’t know this, then we need to understand the water usage in the building. For example, the number of baths, showers, sinks, dishwashers, washing machines and toilets. The static head in the building, the power supply, available space for the pump set and number of pumps required, along with the flow and pressure will help determine the size of the set required.
Our booster sets can be supplied with a wide range of accessories and manufactured bespoke for your needs. They can be fitted with up to 6 pumps, along with WRAS approved break tank, AB Air Gap, powder coated baseplate, metal frame, manifolds, valves, fittings, gauges, press control, inverter drives, pressures vessels and control panels.
Our inverter drives vary the speed and performance of the pumps and can also protect the pumps. They have dry run protection; this cuts out the pump in the event no fluid is entering the pump head. They also have over current protection and over temperature protection for the motors.
The Water Regulations Advisory Scheme (WRAS) is a standard set of by the water regulations board in the United Kingdom. WRAS is a mark that shows that a component used with water in a public water supply complies with this standard.
