PRODUCT INFORMATION

ROBUST AND COMPACT FOUR STAGE HOME PRESSURE SYSTEM

Applications: Ideal for pumping clean, non-volatile liquids without fibres or solids in such applications as household water supply, irrigation, water transfer, washing systems and pressure boosting.

FEATURES & BENEFITS

The HS Series pressure systems consist of an HS pump fitted with a Torrium2 controller. The Torrium2 is supplied connected electrically to the HS pump motor for:

• Easy non-tradesmen installation and assembly
• Positive safety under varied weather conditions

The combination of the high pressures supplied by the multistage HS pump and constant flow control provided by the Torrium2 enables consumers to enjoy the benefits of a strong comfortable shower from a pump that does not cycle plus the reliability of adaptive technology.

The complete HP Pressure System is compact and quiet providing for:

• Easy installation, especially where space is at a premium
• Non-intrusive operation, for consumer enjoyment

All parts of the entire system that are in contact with the water are manufactured from safe, corrosion resistant materials for:

• Consumer confidence that their water supply will be as good coming out as it was going into the system
• Ability to use the HS pressure system on a variety of water qualities
• Compliance with the strict requirements of ISO 9001.2000 quality standards ensures consistency of quality of the system
• Air purging valve for easy installation and priming

PUMP

High efficiency, quiet “half blind” impeller in 4 stage design in two flow rate ranges for:

• More pressure in home outlets
• Choice of performance options to suit most homes
• Quieter household environment
• Improved waterway clearances to reduce impeller blockages

Impeller have dual shaft flats for positive drive and long life, especially important for household pressure systems where pumps are required to stop and start many time during their life.

Patented floating impeller neck rings help improve efficiency and reduce hydraulic noise providing better performance with less noise.

304 stainless steel casing, pump shaft and diffuser baffle returns provide long life and ability to withstand pressure variations. Special in-built air purging valve helps remove air from the pump and suction during original priming and also during normal operation, thus:

• Makes original installation quicker and easier
• Reduces the chance of pump operating in a partial prime condition

High quality, low-drag mechanical shaft seal for long life and reliable starting.

MOTOR

The Davey manufactured TEFC motor has an IP55 enclosure providing:

• Excellent corrosion resistance
• High levels of resistance to dust and rain

All HS pump motors are class F insulation rating and have higher than normal ambient temperature ratings of 50ºC, providing for longer life, improved tolerance to voltage variations and peace of mind, even on the hottest days.

Permanently split P2 ‘fail safe’ capacitor design:

• Reliable starting even in low voltage circumstances.
• Superior frequent starting performance
• Single phase motors are protected against both high operating temperatures and high current by a built in, automatically resetting thermal overload
• Double contact C3-HTG sealed bearings for quieter running and longer life
• Corrosion resistant feet on motor shell, include three point bolt-down facility
• Standard models are 220/240 volt, 50Hz, single phase. HS models in 60Hz 110/115 volt and 220/230 volt single phase available on request
