LMI Series A/B/C Chemical Metering Pumps

LMI Series A, B and C Chemical Metering Pumps have been an industry standard for over 20 years. The familiar yellow and black chemical metering pumps have a rugged, totally enclosed, chemically resistant housing for protection in the harshest environments. Encapsulated electronics and a rigid housing and stroke bracket ensure years of precise, repeatable performance with these LMI chemical metering pumps. Several control options are available for all applications and budgets:

Type "9" control is designed for easy integration into chemical feed systems. The stroke rate may be controlled manually or by an external signal generated by a flowmeter, controller, transmitter, PLC or other device with these LMI chemical metering pumps. Divide or multiply a digital (pulse) input or program a response to a milliamp (4-20, 0-20, 20-4, 20-0) input. Remote on/off and low level inputs are standard. The clear liquid crystal display provides the user with operational status. The unique 5-level power control reduces system shock and extends the life of the pump. The optional Digi-Pulse Flow Monitor verifies chemical flow and provides an alarm output on these LMI chemical metering pumps..

Type "1" control is designed for accurate chemical feed where manual or on/off control is all that is required. Dual manual control of stroke speed and stroke length are provided with this LMI chemical metering pump model.

LMI Series P Chemical Metering Pumps

The Series P Metering Pump is designed for more economical chemical injection. The totally enclosed, chemically resistant housing and encapsulated electronics provide the performance and long life that you've come to expect from an LMI Chemical Metering Pump. The compact size and wide range of outputs makes it ideal for OEM applications. Dual manual control of stroke speed and length and fixed speed versions are available for simple manual or on/off control.

LMI Series E7 Explosion Proof Electronic Metering Pumps

The Series E Chemical Metering Pump is designed for use in hazardous environments. chemical metering pump meets or exceeds all standards for Class I, Division I, Groups C and D; Class II, Division I, Groups E, F and G. The rugged, urethane coated, cast housing and encapsulated electronics provide excellent chemical resistance and long life. The stroke speed may be controlled manually or externally by a digital input or a milliamp input with the use of an A to D converter.

LMI Series H9 High Pressure Electronic Chemical Metering Pumps

The Series H9 Chemical Metering Pump is designed for very low output injection into high pressure systems. An electronic pump with a 316 S.S. packed plunger liquid end provide users with all the advantages of an electronic pump in applications where previously only motor-driven pumps could be used. Type "9" control is standard with the stroke speed manually controlled or externally controlled by a digital or milliamp input.

LMI Series J5 12VDC Electronic Chemical Metering Pumps

The Series J5 Chemical Metering Pump is designed for remote applications where AC electrical power is unavailable. The low power consumption (1.6 amp average current draw or 19 watts at maximum speed) makes this chemical metering pump ideal for agricultural and solar powered installations. Manual control of stroke speed and stroke length or external control of stroke speed by a digital input for flow proportional applications.

LMI Series M Motor-Driven Chemical Metering Pumps

The Series M Chemical Metering Pump is designed for applications where higher outputs are required than an electronic pump can deliver. The Series M features a mechanically actuated diaphragm and a totally enclosed motor. The compact, urethane coated cast housing provides durability in harsh environments. Stroke length is manually adjusted. An optional motor controller is available for external control by a digital or milliamp input for this chemical metering pump.

LMI Series G Motor-Driven Chemical Metering Pumps

The Series G Chemical Metering Pump is designed for high output applications. The drive incorporates a variable eccentric 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. DC variable speed drives are available for external control and automation.
