5 Litre Chemical Dosing Pot

Dosing pots are required in order to feed liquid chemicals such as corrosion inhibitors into closed systems. The dosing pots consist of a stainless steel vessel with inlet (return) and outlet (flow) valves, a drain valve and a filling valve. A stainless steel tundish, air release valve, wall mounting brackets and a non-return valve.

Closed re-circulating water systems (chilled or hot water) can be simply dosed on a regular / manual basis by use of these dosing pots. Fitted across flow and return lines, they provide a means to annex a portion of the system water which can be drained away and replaced with the chemical to be dosed. When re-connected to the system, the chemical is flushed through.

The dosing pots are fitted with large 1" valves, which ensure quick and easy action of the pot even in low flow/pressure conditions. An air vent valve enables the pot to be purged during filling thus eliminating undesirable air ingress to the system. A NRV check valve is fitted into the fill line below the tundish.


  • Stainless steel shell & tundish
  • Welded to BS EN 287

All chemical dosing pots that are designed to PD 5500:2009 category 3 (CE marked) have the following Max. Working pressures.

14 bar 3.5 litres to 6 litres inclusive.
10 bar 10 litres to 20 litres inclusive.
8 bar 25 litres +

Chemical Dosing pots that are not designed to the right are available which have max. working pressure of 14 bar throughout the range (3.5 litre to 25 litre).


It is important that the dosing pots are fitted correctly in to the system to allow rapid chemical feed. This is best achieved by connecting across the main flow and return pipe work. Ideally the flow connection should be made on to the bottom of the dosing pot (valve C), and the return the top (valve B).

The dosing pot is designed for the conditions stated on the name plate, the system into which the dosing pot is installed should have adequate protection to ensure the dosing pot is operated within these limits at all times.


  • Isolate pot: close all valves
  • Drain pot: open valves A and D
  • Charge pot: close valve D and introduce solution via valve A (tundish)
  • Expel air: open air vent until solution appears
  • Inject treatment: close valve A fully and open valves B and C.
  • The dosing pot may reach temperatures up to 120 degrees centigrade.
  • Protection or warnings should be applied to ensure that personnel do not come into contact with the
  • pot so as to avoid burns.
  • A check valve is installed to prevent accidental scolding and chemical saturation (blow back) of
  • personnel operating the dosing pot.
