Plunger Metering Pumps
API 675 – MET 2 Type
The MET 2 metering pump covers the range of the medium and large capacities in the dosage and injection applications.
The pump is a positive return type and is designed for continuous service.
During operation or standstill of the pump the stroke is continuously adjustable by means of a manual knob or by automatic control systems, pneumatically or electronically driven.
The stroke variation is proportional within the whole adjusting range of 0-100% and guarantees linearity and repeatability of the flow in accordance with API 675 requirements.
Special executions for less than 1 l/h and pressure up to 1500 bar are available.
For the hydraulic end there are two versions available: plunger and diaphragm.
The diaphragm head is hydraulically actuated and the diaphragm is double with a monitoring system which allows failure detection.
