The MET 1 metering pump covers the range of medium capacities in dosage and injection applications.
The pump is a positive return type and is designed for continuous service. Its design allows the installation of a double acting arrangement to obtain very large capacities. 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. For the hydraulic end there are two versions available: plunger and diaphragm. The plunger head is hydraulically actuated and the diaphragm is double with a monitoring system which allows failure detection.
