C721-277 LMI Series C Chemical Metering Pump 96 GPD – 100 PSI- 115V

LMI Series C Metering Pump.
96 GPD – 100 PSI, Liquid End 277, 115 VAC 50/60 Hz, US Plug.

Pulse Input with Dual Manual Control
Stroke frequency control via pulse signal input, manual stroke length control. Stroke frequency is manually adjustable when in local control. Includes low level float switch input.

General Description
Positive displacement, Liquifram type, UL and CUL authorized chemical metering pumps from LMI Series C are required (Series C76, C77, and C78 not UL or CUL approved). While the pumps are operating, the output volume must be able to be adjusted from zero to the maximum capacity.

Drive Assembly
All moving components of the pump drive must be completely enclosed. To ensure optimal protection against chemical spills, electronics must be kept inside a chemical-resistant enclosure located at the back of the pump. Under maximum pressure and full speed settings, the maximum amount of electrical power that can be consumed in an hour is 44 watts (87 watts for Series C76, C77, and C78). A pump’s weight cannot be more than 20 pounds (9.1 kg) or 28 pounds (12.7 kg) for models C76, C77, and C78.

Pump Controls
Control of Series C7 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 C7 units shall accept signals without the use of electrical timer or internal timer. Pressure capacity shall be adjustable to reduce noise, vibration and wear.

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%.

Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant glass fiber reinforced thermoplastic with a glass fiber reinforced polypropylene EPU carrier (with plastic coated cast iron EPU carrier for Series C76, C77 and C78). All exposed fasteners shall be stainless steel. Valve seat and seal ring shall be renewable by replacing only the combination seat-seal ring or 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).

Applications:
