Images are for representation only. Actual product may differ in size, color or options.
LMI Roytronic Excel Series AD Metering Pump.
2 GPH @ 50 PSI, 230 VAC 50/60 Hz, US Plug.
(Molded FastPrime Head, Double Ball Check Valves)
Pulse/Analog Input with Dual Manual Control - Digital
Pulse or 4-20 mA signal input controls frequency, LCD display, manual stroke length control, frequency manually adjustable when in local control, pulse multiply/divide functions, 24 V output for remote device. Includes dual low level float switch input. Display configurable to indicate theoretical pump flow.
General Description
LMI Roytronic Excel Series AD chemical metering pumps shall be positive displacement, Liquifram type pumps. Relevant models are UL/CUL or CE certified. Output volume shall be adjustable while pumps are in operation from zero to maximum capacity.
Pump Controls
Series AD8 metering pumps shall have a liquid crystal display to indicate stroke speed of the pump and theoretical flow. Control shall be selectable between internal and external modes as well as stroke frequency adjustment by means of a tactile keypad. Adjustment for stroke length shall be by means of a readily accessible dial knob. A pulse indicator light shall flash green between strokes when pumping in internal mode, and yellow between strokes when pumping in external mode. When in external mode, Series AD8 units shall accept 4-20 mA input signal or external pulse signal for control of pump speed. The pump shall be capable to support external connection requirements for remote start/stop or pulse divide/multiply functions or a power supply for remote powered devices. The pump shall be equipped with an on/off button and a dual low level float switch input. When the dual low level sensor registers empty, the low level indicator light shall turn yellow when a low level is registered and red when an empty level is registered. The pump shall turn off when it registers an empty level. The pump shall be equipped with a universal voltage supply capability.
Drive Assembly
The pump drive shall be totally enclosed with no exposed moving parts. Electronic pulser shall be supplied with quick connect terminals at least 0.110 inch wide (2.79 mm). Electronics shall be housed in a chemical resistant enclosure for maximum protection against chemical spillage. Electrical power consumption shall not exceed 25 watts per hour under full speed and maximum pressure conditions. Pump weight shall not exceed 10 lbs (4.75 kg).
Pressure Relief
Models with the LMI 4-Function Valve installed on a FastPrime or AutoPrime Liquid End are recommended to provide automatic pressure relief.
Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant glass fiber reinforced thermoplastic. All exposed fasteners shall be stainless steel. Chemical metering pump valves shall be ball type. 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).
