Hammelmann pumps in detail

High flow pump head

High flow pump head

Pump models HDP 380, 500, 800 and MC with plunger diameters of 90 mm and above are outfitted with high flow pump heads.

These were especially developed to handle very high volumes and distinguish themselves from other Hammelmann pump heads by having side mounted valve sets.

This design concept enables the use of valves with very large cross section dimensions which results in low flow velocities and consequently greatly reduced wear.

The valve sets and plungers can be easily accessed for maintenance by simply removing a top cover plate.
