Hydraulic Diaphragm Metering Pump HYDRO API

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.

Your benefits

The permitted rated flow configuration is possible in the stated range when pumps are selected in accordance with API 675 (control range 1:10).

The litre capacity indicated using […] is the maximum litre capacity with an applicable control range of 1:5 and does not therefore satisfy API 675.

Example: with 52 mm piston, 10 bar pressure and stroke rate of 136 strokes/min results in (200) – 276, i.e. the control range of 1:10 is met for a rated flow of between 200 l/h and 276 l/h.
