Series AA Information

General Description
Chemical metering pumps shall be positive displacement, Liquifram“ type pumps that are UL, CUL and CE approved. Output volume shall be adjustable while pumps are in operation from zero to maximum capacity of: AA17, AA77, AA97 - 0.42 GPH (1.6 liters per hour) AA14, AA74, AA94 - 0.58 GPH (2.2 liters per hour) AA18, AA78 - 0.75 GPH (2.8 liters per hour) AA15, AA75, AA95 - 1.0 GPH (3.8 liters per hour) AA16, AA76, AA96 - 2.0 GPH (7.6 liters per hour) Chemical metering pumps shall be capable, without a hydraulically backed diaphragm, of injecting solutions against pressures up to: AA14, AA74, AA94 - 250 psig (17.3 bar) AA17, AA77, AA97 - 140 psig (9.7 bar) AA15, AA75, AA95 - 110 psig (7.6 bar) AA18, AA78 - 80 psig (5.5 bar) AA16, AA76, AA96 - 50 psig (3.5 bar)
Pump Controls
Adjustment shall be by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are to be located opposite the liquid handling end. On-off switch shall be integral with frequency control, "off" position to be below lowest frequency setting.
Drive Assembly
The pump drive shall be totally enclosed with no exposed moving parts. Solid state electronic pulser shall be fully encapsulated and supplied with quick connect terminals at least 3/16" (4.75 mm) wide. 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 22 watts per hour under full speed and maximum pressure conditions.Pump weight shall not exceed 14 lbs (6.5 kg).
Pressure Relief
To eliminate need for pressure relief valve, Liquifram TM shall automatically stop pulsating when discharge pressure exceeds pump pressure rating by not more than 35%.
Materials of Construction
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, with Ceramic Balls. Valve seat and seal ring shall be renewable by replacing the combination seat-seal ring or cartridge valve assembly. Pump head shall be of transparent acrylic material capable of resisting the pumped chemical. Fittings and connectionsat pump head shall be PVC.
Check Valve / Tubing Connections
A total of 16 ft (4.8 m) of polyethylene Tubing shall be provided per pump complete with compression connections. A foot valve with integral one piece strainer shall be provided for the suction line, and an injection check/back pressure valve with 1/2" NPT male connection for the injection point. The injection check valve shall incorporate a dilating orifice which prohibits scale formation and accumulation of crystalline deposits.
