ProMinent - Model HYDRO API -Hydraulic Diaphragm Metering Pump
Capacity range of single-head pump: 7 – 1,506 l/h, 100 – 7 bar - The HYDRO API 675 is an extremely robust hydraulic diaphragm metering pump, which meets the most exacting safety requirements and is designed in accordance with API 675. This is ensured by the PTFE multi-layer diaphragm with diaphragm monitoring, the full-motion drive and automatic bleeding, for example. Its modular construction makes it extremely versatile.
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.
Excellent process reliability:
- PTFE multi-layer diaphragm with integrated diaphragm monitoring with condition signals
- 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 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
- Stroke length: 15 mm (HA1a, HA2a, HA3a), 20 mm (HA4a)
- Rod force: 2000 N (HA1a, HA2a), 4200 N (HA3a), 5800 N (HA4a)
- Stroke volume adjustment range: 0 – 100%
- Stroke volume adjustment: manually using scaled rotary dial (with electric actuator or control drive as an option).
- The dosing precision is better than ± 1 % within the 10 – 100 % stroke volume range under defined conditions and with correct installation
- PTFE multi-layer diaphragm with electrical diaphragm monitoring with condition signals sent via contact
- Integrated hydraulic relief and vent valve
- Full-motion drive
- Wetted materials: PVDF, PTFE+25% carbon, stainless steel 1.4571, Hastelloy C.
- A wide range of power end/drive versions is available: Three-phase or standard three-phase motors or motors for use in areas at risk from explosion, different flange designs for use of customer-specific motors
- Degree of protection: IP 55
- Design in compliance with API 675
