Both knobs are to be located opposite the liquid handling end. A pulse indicatto light will flash green when pumping. The pump shall be equipped with an on/off button.
Drive Assembly
The pump drive shall be totally enclosed with no exposed moving parts. Electronics shall be housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Electrical power consumption shall not exceed 42 watts per hour under full speed and maximum pressure conditions. Pump weight shall not exceed 10 lbs (4.75 kg).
Pressure Relief
The LMI 4-Function Valve is recommended with a FastPrime or AutoPrime Liquid End to provide automatic pressure relief.
Materials of Construction
Chemical metering pump housing shall be of chemically resistant glass fiber reinforced thermoplastic. All exposed fasteners shall be stainless steel. Valves shall be serviceable by replacing the cartridge valve assembly.
Check Valve / Tubing Connections
A total of 16 ft (4.8 m) of tubing shall be provided per pump complete with compressing connections (on models with tubing connections). A foot valve with integral one piece strainer shall be provided for the suction line (on non-high viscosity models with tubing connections), and an injection check/back pressure valve with 1/2" NPT male connection for the injection point (on models with tubing connections).
