Pumps: Chemical Injection Diaphragm Pumps by: Liquid Metronics, LMI, Milton Roy   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:

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. 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.

Type “7” control is designed for more economical systems. 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.

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.
