LMI Series B Chemical Metering Pump

LMI SERIES B

CALL FOR PRICING AND DELIVERY OPTIONS

The LMI Series B Chemical Metering Pump has been an industry standard for over 20 years, delivering rugged reliability in the harshest industrial environments. This solenoid-driven pump features a totally enclosed, chemically resistant housing, making it ideal for corrosive chemical dosing in metal finishing, electroplating, anodizing, water treatment, and chemical processing. With flow rates from 1.4 to 45 GPH (5.3 to 170 LPH) and pressures up to 250 psi (17.2 bar), it offers adjustable stroke frequency and a 1000:1 turndown ratio for precise control. Encapsulated electronics and NEMA 4X/IP65 enclosures ensure long-term performance, while options like external pacing and low-level switches enhance versatility for municipal and industrial applications.
