to 500 l/h
LMI mechanical diaphragm metering pumps are heavy-duty - up to 12 bar can be achieved with a maximum flow rate of 500LPH.
The pumps have a mechanically actuated PTFE diaphragm and are lubricated for life, with a sealed housing that reduces wear.
The pumps stroke lock maintains ±2% accuracy of flow for stroke settings between 10 and 100%. There is a choice of PVDF or stainless steel pump heads.
These motor-driven diaphragm pumps are designed for high-output applications. The drive incorporates a variable design which ensures smooth output and reduces system shock.
The mechanically actuated diaphragm reduces the possibility of hydraulic oil contamination of process liquid, which makes this an ideal pump for water treatment applications.
Flow rates can be manually controlled by adjusting the stroke length. For a 4-20mA remote control option, use the Varipulse motor controller (ordered separately) and a metering pump with a 415 VAC, three-phase motor.
The package includes PVDF pump heads with flow rates up to 44LPH supplied with injection nozzle, foot valve, weight, 6m polyethylene tubing, and a 6m reinforced PVC hose.
