K | KBL Series Peristaltic Metering Pumps - 158 GPH
Description
LMI's KBL Series Peristaltic Metering Pumps provides chemical feed flow rates to 160 GPH or pressures up to 110 psi (at lower flows). The pump drive and tubing can be configured for optimal performance based on application flow, pressure, and chemical. All three (3) drive options KBL2, KBL3, and KBL4 use an internal brushless DC motor and can be configured with SCADA or Modbus control for remote communication and multiple I/O options. Three (3) tube materials are coded (A) Extended Life (XL) which is resistant to most acids, alkalis, and oxidizing agents (B) Chemical Resistant (CR) which is resistant to strong acids, bases, commercial sanitizers & cleaners, and (C) Petro-Tough (PT) which is ideal for fats and oils, lubricants, and some solvents

Tube Material Information

XL - Extended Life

LMI XL is best for fatigue life and is the longest-lasting tube in compatible applications. XL has excellent acid and alkali resistance, and is compatible with numerous oxidizing agents such as sodium hypochlorite. Min/max temperature: 0-80°C (32-176°F).

CR - Chemical Resistant

Suited for handling strong acids and bases, and is virtually unaffected by most commercial sanitizers & cleaners. Min/max temperature: 0-54°C (32-130°F).

PT - Petro-Tough

Can be used with fats and oils, lubricants, and some solvents. Min/max temperature: 0-54°C (32-130°F).
