Page 3: Installation
Locate the pump in an area that is convenient to both solution injection point and electrical supply. LMI Series E7 metering pumps have corrosion resistant housings, but should not be subjected to continuous high temperature (over 122° F or 50° C). -
Page 4: Prevent Syphoning
The external trigger circuit is isolated and has the same characteristics as the other LMI Control Code 7 Series metering pumps. Minimum time in low impedance state (on) is 50 milliseconds. Minimum time in high impedance state (off) is 100 milliseconds. -
Page 5: Wiring For Accessories
E7 Series metering pumps come equipped with four external control wires for operating the complete line of LMI accessories. Since hardwiring is essential for operating devices in hazardous locations, removal of the four pin connector from the accessory is necessary. The chart below indicates proper wiring for each accessory. -

Max. Pressure Rating Max. Output Series G PH 20.7 10.3 15.1 20.0 PROCEDURE FOR ON-SITE VOLUMETRIC CALIBRATION E7 IN INTERNAL MODE Make certain speed control knob is turned fully clockwise. Turn off power to pump. With pump primed and discharge tubing connected to the injection point as it would be in normal service, place foot valve and strainer assembly in a graduated container with a volume of 500 ml or more (so that the volume displaced by tubing and foot valve assembly is minimal in relation to volume of the solution in the container). -
Page 7: Troubleshooting Liquid End
2.0 TROUBLEShOOTING LIQUID END 2.1 LOW PUMP OUTPUT Low pump output can be caused by many things. Some of the more common ones are: • Very low stroke setting, i.e. red zone setting of knob • Trapped air in pump head (trapped air in discharge tubing has no effect) •... -
Page 8: Excessive Pump Output
Ruptured pumping diaphragm—If rupture is severe and pump is injecting into pressure, solution leak will be obvious through the 3/16” (5 mm) diameter hole at the bottom of the spacer directly behind the pump head. Replace pumping Liquifram™ (diaphragm). If rupture is a small pin hole, there may be oozing of solution through the 3/16”... - Page 9 Stroke Setting Model Length E70, E71, E72 90% E73, E74 • With pump stroking, screw on new Liquifram™ until the center part begins to buckle inwards during the latter half of the stroke. Turn pump off and check Liquifram™ position with a straight edge according to Figure 6 (below).
