It depends on the application. We recommend performing maintenance every six to twelve months. This feature allows you to adjust the power capacity, which reduces noise, shock and vibration in the system. It also prolongs the pump's life. Motor-driven pumps must be installed with a pressure relief valve.
Electronic pumps have inherent pressure relief.
If the pressure exceeds the pump's capacity, it will stall without damage to the pump. LMI electronic metering pumps are simple to control from an external signal. By using an LMI pump with an RFP Remote Flowmeter Pulser, the speed of the pump will be controlled by the flow rate of the water. LMI has a worldwide network of distributors that stock and service the complete line of LMI products. Click here for our Y2K statement.
