Water Pump 0.75 l pressure accumulator tank, 1/2" - for motorhome and boat water systems
- 0.75 l accumulator tank with internal bladder: smoother flow, less pump cycling and a quieter system. Pre-charge 0.7 bar, max. 8.6 bar, 1/2" NPT ports. 2 hose barbs included.
Water Pump 0.75 l accumulator tank is installed after a water pump with a pressure switch. The internal bladder with an air cushion stores water under pressure, smooths the flow and reduces frequent pump cycling. For motorhomes, caravans, boats and cabins.
What it does
- smoother water flow
- less on/off cycling of the pump
- quieter system and longer pump life
- more stable hot water temperature with instant water heaters
- fits new and existing systems
How it works
- factory pre-charged air cushion behind the bladder
- while the pump runs, water enters the tank; at maximum pressure the pump stops
- when a tap opens, the air pushes water into the system, and the pump only restarts when pressure drops to the minimum
Installation
- disconnect the pump power and open a tap to relieve pressure
- the tank goes anywhere in the discharge line after the pump, in any position
- secure the hoses on the barbs with hose clamps
- restore water and power and bleed the air by running water through to the last outlet
- rubber feet, 2 hose barbs included
System diagram
Water flows from the water tank to the pump, and after the pump through the accumulator tank to the water heater and taps.
Pre-charge pressure
- factory set to 0.7 bar
- before use, set the air pressure 0.2 bar below the pump cut-in pressure
- adjust with an ordinary tyre pump and gauge at the car-type valve on the tank end, with the pump off and a tap open
- check the pressure regularly
