The Water Mist Pump

When seeking a custom water mist pump to protect your property that delivers to recognised and approved industry standards, the decision to engage with IPH should be a simple one.  Our sleek compact pump unit can be connected directly to the mains water and includes an on board monthly self-test and manual test facility. The control board monitors the pumps and is equipped with fire and fault N/O and N/C relays for use with third party equipment (e.g. alarms and fire panels).

Specifications & Features

Fire Resistance – The pump enclosure is now completely constructed from steel providing fire resistance and additional resistance against mechanical damage.

Serviceability – The new pump has a removable cover so that the internal components can be serviced and maintained in the field by the installing company. Pumps can now be repaired in the field rather than being sent back to the manufacturer which will save on costly revisits.

Integrated Inlet/Outlet Manifolds – All of the inlet manifold (Strainer, low pressure switch, actuated ball valve) and outlet manifold (isolation valve, pressure gauge, drain valve) are now integrated within the enclosure. No more untidy valves and hoses.

No permanent drain required – Operation of the pump is no longer requires a permanent drain to be provided.

Wall or floor mounting – If fitted on the floor or in a cupboard the enclosure has a flat back which fits neatly against a wall. Fixing holes are provide in the back of the chassis for optional wall mounting.


What is the working pressure of the Pump?

Our Pump run pressure can be adjusted from 10 – 100 bar to suite different nozzles which may be used for protection of different applications.

Low Standing Pressure – The system now operates off a flow switch rather than a pressure switch. This means that the system will eventually drop down to mains water pressure and sit there indefinitely without calling the pumps to work. Previously any loss in pressure due to a small leak in the distribution pipework could cause the pumps to come on at undesirable times. Now the system sits at mains water pressure and will not bring the pumps on unless there is a significant flow of more than 0.5lpm.

Actuated ball valve – Previously after the pump had finished its run time it would cut power to the pumps however it would still be able to run indefinitely at mains water pressure. We have now integrated an actuated ball valve which will shut off the water supply and the power to the pumps following elapse of the selected run time.

Drip tray with float switch – There is always a risk of damage to products during transit or installation. The risk of damage to property as a result of internal components leaking is almost eliminated with the addition of a drip tray and float switch within the base of the pump enclosure. In the event of any escape of water from damaged components the float switch will operate and close that actuated ball valve to shut off the water supply to the pump.

Corrosion resistance – The internal pump components are now made of the highest quality corrosion resistant materials.

Robust operation – There are no solenoid or pressure relief valves that run to permanent drain. This avoids any problems associated with dirt under the seals which could result in a small escape of water and pumps running at undesirable times.

Adjustable pump run time – The pump runtime can be adjusted with a dil switch to suit 30min (Residential) or 10min (Domestic) depending on the category of the system.

Pre-action / Double Knock Operation – With any water based fire suppression system there is always risk of unwanted operation through accidental or malicious damage to pipework or nozzles/sprinklers. The discharge of water could be potentially damaging to the property the system is protected.



Full Spec + Sizing

A compact unit that includes self testing,  means you only need to service once a year. IPH Mist Suppression Ltd can offer a full service contract with all design and  installations.

As an additional safety measure to protect against unwanted operation and ultimately needlessley misting up your property, our custom made pump incorporates safety facility to receive an input from the smoke detection system on the pump control and monitoring board. When using this facility, the pumps would need to have both the smoke detection and the nozzle operate before the pumps will run.

If just the nozzle operates, the system will not run. If just the smoke detection operates the system will not run. Both smoke (to operate the detection system) and heat (to operate the nozzle) will need to be present for the system to run.

Whilst this is an optional facility we would recommend that you use this on every installation to provide an additional level of protection against unwanted operation. The smoke detection system must be compliant with BS5839 pt6 Grade D LD1 with detection provided in every room that is protected by the mist system.

Increased Fire Safety Measures


Following recent Government Legislation change (May 2020), fire suppression systems are now regarded as a mandatory requirement for a wider range of residential and domestic properties and apartment blocks that marks the greatest change to building safety systems in a generation!

What are the 2 parts of PAS 79 2020

PAS 79, which was last revised in 2012, provided generic fire risk assessment guidance. However, the housing sector wanted more housing-specific recommendations to be developed. It was therefore decided to revise PAS 79, updating the existing PAS and renaming it as Part 1, and introducing a new, housing-specific, Part 2.
