Variable Round-The-Pump Proportioner

Delta Fire Ltd

The Delta Variable Round-The-Pump Proportioner has become a popular product within Delta Fire’s fixed foam equipment range. This foam inductor produces pre-mix solution for one or more foam making branchpipe and can be calibrated to suit the client’s requirements.

This proportioner is very compact and robust and can be fitted to a fire pump as a temporary or permanent feature. The inductor has an induction flow range of 0 to 90 litres per minute calibrated in increments of 9 litres per minute and can also be used in a By-Pass type system.

Delta’s Variable Round-The-Pump Proportioner is supplied complete with left and right hand labels together with a general label that has no scale allowing for ‘customer specific’ calibration. The required calibration setting within a range is selected by rotating a knurled twist-grip handle.

The Inductor is made from corrosion resistant material throughout and although normally used in a fixed pipework system, various ancillary components are available to facilitate temporary installation on the majority of fire appliances.

Manufactured in the UK under an ISO9001 Quality System the Delta Variable Round-The-Pump Proportioner is a key component in Delta’s fixed foam equipment range.
