General Description:
LMI Series B chemical metering pumps shall be positive displacement, Liquifram type pumps that are UL and CUL approved. Output volume shall be adjustable while pumps are in operation from zero to maximum capacity.

Pump Controls:
Control of Series B7 metering pumps shall be selectable between internal and external pulsing by means of a 3-position center-off switch. Stroke length shall be adjustable by means of readily accessible dial knob. When in external pulsed mode, Series B7 units shall accept signals without the use of electrical timer or internal timer. Pressure capacity shall be adjustable to reduce noise, vibration and wear.

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 29 watts per hour under full speed and maximum pressure conditions. Pump weight shall not exceed 15 lbs (6.9 kg).

Pressure Relief:
To eliminate need for pressure relief valve, Liquifram shall automatically stop pulsating when discharge pressure exceeds pump pressure rating by not more than 35%.

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).
