Davey HM Series with Torrium2


The HM Water Pressure System range with Torrium2 controller is a premium product designed for multi-storey buildings and homes with high pressure needs.With all stainless-steel pump and hydraulic componentry, and the ability to sustain high water temperatures, the HM Water Pressure System is ideal for household and domestic water supply, farming and agricultural use and irrigation or turf watering applications.The HM 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.
Automatic pressure system for household and domestic
water supply, farming and agricultural water systems,
irrigation and turf watering systems and automatic
general water transfer.

The economical HM range with Torrium2 allows for maximum flow rates of 250 lpm, and up to 69m head, the HM range has axial suction and vertical discharge with a compact design for ease of install.

Features include:

  • All stainless-steel pump componentry for better corrosion and abrasion resistance, low noise output and reduced power consumption
  • Air purging valve and stage porting for easier priming, and less susceptibility to air leaks
  • Impellers are mounted directly on to the extended motor shaft maximising performance per stage, and increased wear resistance – leading to a long motor + pump life
  • Complete stainless casing attached to motor bracket at 8 points with an o-ring seal, for better sealing
  • Totally enclosed fan cooled (TEFC) electric motor with built in thermal overload protection and automatic reset

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
