LMI Metering Pumps for Chemical Injection

LMI Metering Pumps for Chemical Injection

LMI Chemical Metering Pump Injection Dosing PumpLMI 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 AA, B & C Type “7” :  The stroke rate may be controlled manually or by a digital input. The optional Micropace Control Modules enable the user to divide or multiply a digital input or respond directly and proportionally to a 4 – 20 milliamp input. A low level input is standard.

Series AA, B, C Type “1”  is used when manual or on/off control is all that is required. Dual manual control of stroke speed and stroke length are provided.

The Series P Metering Pump is designed for more ecomomical chemical injection. Dual manual control of stroke speed and length and fixed speed versions are available for simple manual or on/off control.
