All metering pumps flow rates are referred to 230 VAC
(50-60Hz) and 115 VAC (50-60Hz) mains.
For other power supply (24 VDC/VAC and 12 VDC) please enquire.

Metering pumps are provided with:
- PVDF injection valve,
- PVDF foot/filter valve,
- PVDF level probe (except for CO models)
- 2 m delivery hose (PVDF, except for V, VA and VMS, VMSA series),
- 2 m suction hose (PVC flexible),
- 2 m outgassing hose (PVC 4x6).
Polymers pump series are provided WITHOUT injection valve, foot/filter valve and level probe.
Pumps with Stainless Steel pump head are provided WITHOUT accessory kit.
Self-venting pumps series have PE outgassing hose.

MF and DC (except VMS MF) pump series are equipped with external level alarm. Optional for the others.

Refer to chemical Compatibility Table.

EMEC standard check ball valves for all pumps series are made of ceramic, except for high viscosity liquid pumps (PTFE check ball valves).
PTFE or AISI 316 check ball valves are available on demand.

V and K series (on some capacities) quiet pump availables.

-10°C-+45°C (14°F-113°F)

Available on MF series pumps input for water meter with Hall effect (on demand).
