Davey HS Series with Torrium2


HS Water Pressure System with Torrium2 offers perfect water pressure with high pressure and low power consumption.Ideal for pumping clean, non-volatile liquids without fibres or solids in such applications as:

  • Household water supply
  • Irrigation
  • Water transfer
  • Washing systems
  • Pressure boosting

The HS water pressure systems have been certified and tested to comply with the requirements of the AS/NZS 4020 standard. The AS/NZS 4020 standard stipulates that products in contact with drinking water do not affect the taste or appearance of the water, do not support the growth of micro-organisms and do not release cytotoxic or mutagenic compounds or metals into the water.

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.

Robust and compact, four stage, centrifugal pump with Torrium2 constant flow control and loss of prime device for automatic water pressure. Designed for medium to large size, single and multi-storey homes with a variety of flow rates:

  • HS50-06T – max. flow up to 80 lpm
  • HS60-08T – max. flow up to 110 lpm

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

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.

To prevent annoying fluctuations in water temperature during
showers, Torrium2 uses its intelligence to provide households
with constant flow to give even water pressure. It does this
with its innovative pressure and flow sensors to start the
pump on a pressure drop and to stop it on low flow (~1 lpm).
This avoids pump cycling when there is continuing household
demand for water.
To give you strong pressure right from the start, Torrium2
is designed to cut in quickly when it senses demand for water.
It cuts in when the pressure has dropped to 80% of the
previous top (shut-off) pressure. It uses its intelligence to
automatically set this cut-in pressure each time the pump
stops. In doing so, it allows the system to automatically
accommodate for variations in pump performance or site
Torrium2 is clever enough to detect the difference between
normal water demand and a small leak in the system, such as
a dripping faucet or a leaking cistern. For very low flows,
Torrium2 automatically adapts to reduce the cut-in pressure,
which can be as low as 50% of its last shut-off pressure. This
significantly reduces pump cycling to improve consumer
satisfaction with the system. If normal flow is required in the
house (>0.5 lpm), Torrium2 will sense this and revert to
normal mode and initiate an immediate pump start.
To easily check the system status, Torrium2 has three simple
LED indicators.
• Red LED – the system is in standby mode
• Green LED – the pump is running
• Yellow LED – fault condition
