For use under high pressure. Top-quality high strength steel, with a gleaming red (RAL 3002) epoxy powder coating - perfect protection and finish. Clamp ring of heavy-duty thermally-galvanised steel. Our flexible EPDM Bladder with rolling action are suitable for use with glycol based anti-freeze addition up to 50%. Exact details are available on request. The nitrogen airvalve is sunk and cannot be damaged due to the cap and extra protective plastic beige coverplate. Uncoated threaded system connection, ensuring problem free connecting.
The main elements of the membrane tank are a metal case of high-quality deep-drawn steel and an elastic membrane made of Butyl Rubber Membrane separating the tank into two chambers - an air (cavity between the metal case and a membrane) and a water one (the internal cavity of the membrane). The air chamber is constantly under a pre-set air pressure. The service life of diaphragm tanks is at least 10 years of continuous operation. The durability of the membrane - at least 100,000 cycles. Dupont (France) materials are used as paint.
Features of the design - the location of the top flange (TOP tanks) provide ease of installation / disassembly of the equipment, virtually eliminates the possibility of air plugs in the water cavity of the membrane, the minimum time required to replace the membrane; small overall dimensions.
Basic Introduction
The pressure vessel is designed to provide a storage facility and pressure reservoir for water at temperatures up to 99ºC. Common uses are in water booster sets, heating pressurisation and fill sets. The vessel incorporates a replaceable Butyl diaphragm mounted in a mild steel shell. This method of construction eliminates any contact between the stored water and the steel shell of the vessel, and is therefore suitable for use with potable water. All units up to and including 25 litre sizes are suitable for a working pressure of 8 bar, larger vessels 10 bar, (except 1000LV)
For Water-Dezhi Series

Regarding Installtion
The vessel is supplied pre-charged with air, but this pressure may require adjustment to suit the site conditions. This adjustment must be made with the vessel isolated from the system, and before filling with water. Air may be vented from, or pumped into, a patent valve which will be found under a black plastic screw-off cover on the shell (sizes up to and including 500 litre) or on a side mounted flange (750 and larger). It will be noted that vessels of 60 litre capacity or larger are manufactured with connections at either end of the vessel shell. The vessel should be mounted so that the system connection is made at the lowest possible point, to facilitate on-site maintenance. The other connection may be fitted either with a air bleed valve, or alternatively with a blanking plug. All pressure vessels should be installed with an isolating valve and drain cock.
Periodic Maintenance
The only maintenance required on this equipment is a periodic check on the air cushion pressure. It is necessary to isolate the vessel from the system, and to drain all water from the tank before making this measurement with a standard tyre pressure gauge from the valve.
Maintaince free models are also available,Please refer to customized Model Or Contact Mr.Tom Lee (Export Models Only)
