Series AA Metering Pumps

• Rigid Stroke bracket assembly for highly accurate / consistent dosing performance.
• Advanced control options for simplified system integration (pulse multiply / divide, 4-20 mA, remote on/off)
• 5-level power control option to reduce system shock and extend the life of the pump
• External pacing for flow proportional applications

Series B and C Chemical Metering Pumps

Series B and C Chemical Metering Pumps have been an industry standard for over 20 years. The familiar yellow and black 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. Several control options are available for all applications and budgets

Series P Chemical Metering Pumps

The Series P Metering Pump is designed for more ecomomical 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 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.

Series E7 Explosion Proof Electronic Metering Pumps

The Series E Metering Pump is designed for use in hazardous environments. It 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.

Series H9 High Pressure Electronic Metering Pumps

The Series H9 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.

Series J5 12VDC Electronic Metering Pumps

The Series J5 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 it 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.

DC5500 Cooling Tower Controller with Remote Programming & Communications

The DC5500 has all of the features of the popular DC4500 Controller(see below); dual biocides & inhibitor pumps control, 0-20,000mS conductivity range, four feed modes, etc. The DC5500 also has the additional features of a second water meter input, three tank level inputs, and most importantly- communications capabilities to download historical data, view real time conditions, and program the controller remotely.

DC4500 Cooling Tower Controller

The DC4500 is a bleed and feed cooling tower controller with dual biocide timers. Standard features include; four feed modes (Feed & Bleed, % of Time, % of Bleed, Flowmeter Pulse), intermittent or continuous sampling, uS or PPM display, flow totalizer, manual test modes, temperature display, biocide cycle of 7, 14, or 28 days, biocide lockout, and conductivity or time-based biocide prebleed. Programming is simple and is accomplished with only three keys. The backlit liquid crystal display and LEDs provide a visual indication of operating conditions and equipment status.

DP5000 pH Controller

The DP5000 pH Controller is designed for a variety of industrial pH applications including water treatment, metal finishing, PCB manufacturing and waste treatment. It provides on/off or proportional (pulse) control of metering pumps for addition of acid or base. Level and flow inputs and alarm outputs are standard. An advanced menu includes special features such as the solenoid dump valve control for batch treatment and a “Point 3” (inflection point) adjustment for fine tuning the control profiles of the metering pumps. 4-20mA output is optional.

DR5000 ORP Controller

The DR5000 ORP Controller is very similar to the DP5000 described above, however, it is designed to control LMI Metering Pumps for the addition of oxidizing and reducing agents. It shares the same features and options as the DP5000 and is often used in water and wastewater treatment, fruit processing and metal finishing.

FS5000 Flow Switch Controller

The FS5000 Flow Switch Controller is designed for use in applications that require flow/no-flow control of metering pumps and other devices. It includes a flow switch and three (3) 115V receptacles that are powered with flow and one (1) 115V service receptacle. Power indicator light, flow indicator light and test switch are included.

Series G Motor-Driven Metering Pumps

The Series G Metering Pump is designed for high output applications. The drive incorporates a variable eccentic 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.
