These new hydraulic motor driven metering pumps, the Hydro/2 and Hydro/3, are designed to offer precise and reliable metering, even under high pressure. Capacities for the Hydro/2 pumps range from 2.2 to 15.3 gph (8.4 to 58 L/h). Capacities for the Hydro/3 pumps range from 6 to 38 gph (23 to144 L/h). Maximum backpressures are 928 or 362 psi (64 or 25 bar).

The Hydro main pump H is driven by 1/2/1 HP motor. Each pump comes with a NEMA 56C flange as a standard. The stroke length is 0.6 in. (15 mm) and can be adjusted within 1% accuracy. It also features cast aluminum housing, and is available with four gear ratios, two liquid end sizes and two liquid end materials. As standard, all pump types are equipped with an integrated hydraulic bypass valve, a multi-layer safety diaphragm and a diaphragm failure monitoring indicator. Under defined conditions and if installed correctly, metering repeatability is better than ±1% within a stroke length range of between 20 and 100%.

The double-headed version is equipped with two liquid ends, which operates in push/pull action, 180° out of phase. Each liquid end is provided with a separate stroke length-adjusting knob, enabling each liquid end to operate at a separate, independent feed rate.

The Hydro add-on pumps can operate as a single or double-headed version.
