For flexible metering with excellent process reliability in the medium pressure range.
The HYDRO API 675 hydraulic diaphragm metering pumps form an integrated product range with stroke lengths of 15 or 20 mm. Equipped with full-motion drive and automatic bleeding, they therefore cover the capacity range of 7 to 1506 l/h at 100 – 7 bar. They also meet the requirements of API 675.
Your benefits
Excellent process reliability:
- PTFE multi-layer diaphragm with integrated diaphragm monitoring with condition signals sent via contact
- Integrated hydraulic relief valve with ventilation function
- The dosing precision is better than ± 1 % within the 10-100 % stroke volume range under defined conditions and with correct installation.
Excellent flexibility:
- 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
The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.
- 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
- Metering of Fluids in Chemical Production
- Incredible versatility: metering pumps in production
- There are various types of metering pumps, but what they all have in common is reliability, robustness and thoroughness. That’s why all our pumps are in demand in chemical production.
- Downstream Oil Treatment
- It’s all about the oil
- Makro diaphragm metering pumps or even the new Evolution pumps are used for emulsion cracking so that the precious oil is perfectly separated from other substances. The pumps are completely autonomous.
- Feed Water Treatment in Energy Generation
- ProMinent-style desalinated boiler feed water
- Our water treatment know-how delivers desalinated and therefore high-quality, ultra-pure boiler feed water. No energy or water is lost with ProMinent.
- Flue Gas Cleaning in Energy Generation
- Flue gas cleaning for fresh air and a clean environment
- ProMinent understands how to incorporate the complex flue gas cleaning process in power plants. Harmful substances are reliably removed from the air before they enter the atmosphere.
- Metering of Fluids
- Incredibly simple and efficient metering of chemicals
- We transport chemicals with ease in any industrial environment: ProMinent solutions store, transfer and meter substances at rates of 0.1 l/h to 100,000 l/h at a pressure of 2 to 3,000 bar.
