Capacity range of single head pump: 11 – 196 l/h; 100 – 10 bar
The Hydro/ 3 API 675 is designed to comply with API 675 due to its technical features, including full-motion drive, automatic bleeding etc.
The hydraulic diaphragm metering pump Hydro/ 3 API 675 (HA3e) meets the requirements of API 675, among other things due to its full-motion drive and automatic bleeding. Some of the many drive options are also approved for use in areas at risk from explosion.
Excellent process reliability:
■ PTFE multi-layer diaphragm with integral diaphragm rupture warning system
■ Integrated hydraulic relief valve with ventilation function
■ Metering reproducibility is better than ± 1% in the 10-100% stroke volume range under defined conditions and with proper installation.
■ The modular construction with single and double head versions permits a wide range of applications, with the double head designs (boxer principle) being operated in push-pull mode
■ It is possible to combine up to 5 metering units, even with different pump capacities, in multiple pump systems
■ 5 different gear ratios are available
Field of application
■ Oil and gas industry.
■ Volume-proportional metering of chemicals/additives in the treatment of boiler feed water
■ Metering of reactants and catalysts in the chemical industry
■ Level-dependent metering of auxiliary agents in industrial production engineering, for instance hot wax metering in the production of adhesive strips
