The company continued to develop and secured contracts in building automatic water pressurisation units for small trawlers and one of the national ship builders. By 1990 Pumpmasters developed their own range of high pressure pneumatically operated pressure test units, many of which were supplied to organisations in the petro chemical and defence industries.

As the cost of water increased the range grew again to include pump systems and water treatment to supply potable water to residential properties and agricultural premises.
