H3 Pumps with overhead mounted motors, views taken on site, O/No. 63210, c.1964

This group of four H3 Pumps were fitted with 1 3/8″ dia. rams, rated for 6000 psi.

The first overhead-mounted-motor version of this pump was introduced in 1963 for this company as a result of a need to minimise the space required for installation. The attached photos ably illustrate this.

Each pump casing was of cast steel with an external fabricated suction manifold allowing for a much higher inlet pressure; a tubular oil cooler was fitted to the oil sump and water jackets encased each side of the crankshaft main bearings. (These photos ably illustrate the cooler mounted in the side of the pump and piping for circulating the cooling water).
