Overview
This document provides detailed instructions for the installation, operation, and maintenance of LMI pumps, focusing on components such as the 4-Function Valve, AutoPrime™ Liquid End, and various installation procedures.

Key Components and Functions
  • 4-Function Valve: Prevents over-pumping and syphoning, provides back pressure, and includes a relief knob for line drainage.
  • AutoPrime™ Liquid End: Automatically removes vapors and gases, ensuring the pump remains primed.
  • Foot Valve: Acts as a check valve to maintain priming in suction lift applications.
  • Injection Check Valve: Prevents backflow and should be installed at the chemical injection point.

Installation Procedures
  • 4-Function Valve Installation: Involves mounting to the pump, connecting tubing, and ensuring proper positioning for pressure relief.
  • AutoPrime™ Liquid End Installation: Requires connecting tubing to the supply tank and ensuring it is not submerged.
  • Foot Valve Installation: The valve must be positioned vertically and slightly above the tank bottom to avoid sediment.

Start-Up and Priming
  • With Multi-Function Valve: Involves setting speed and stroke knobs, opening the relief side, and ensuring the pump is primed.
  • Without Multi-Function Valve: Similar steps as above but without the relief valve adjustments.
  • AutoPrime™ Heads: Utilizes the AutoPrime™ valve to purge air and ensure priming.

Output Adjustment and Calibration
  • Output is calculated based on maximum pump output, speed, and stroke settings.
  • Calibration involves measuring output over time and adjusting speed and stroke as necessary.

Maintenance and Spare Parts
  • Regular maintenance includes replacing elastomeric parts like the Liquifram™, cartridge valves, and seal rings.
  • Depressurizing the discharge line is crucial before maintenance.

Safety Precautions
Always wear protective clothing and equipment when performing maintenance or handling chemicals.
Specifications and Procedures
This document provides detailed procedures for maintaining and troubleshooting LMI metering pumps. Key procedures include flushing the pump head with water or a neutralizing solution, replacing the Liquifram™, and ensuring proper alignment and installation of pump components. The document emphasizes the importance of wearing protective clothing and following safety precautions during maintenance.

Liquifram™ Replacement
The process involves setting the stroke knob to zero, removing the old Liquifram™, and installing a new one. The Liquifram™ Stroke Setting Chart provides specific settings based on pump series numbers. Proper alignment and tightening of screws are crucial to ensure optimal pump performance.

Cartridge Valves and Seal Rings Replacement
Instructions for replacing cartridge valves, seal rings, and injection check valve springs are provided. The document stresses the importance of noting the orientation of valves before disassembly and following the instructions included with replacement kits.

Troubleshooting
The troubleshooting section addresses common issues such as pump not priming, losing prime, leakage, low output, and failure to run. Solutions include checking power supply, ensuring proper installation of components, and replacing worn parts. The document provides specific guidance on adjusting the stroke knob and checking the pump for proper zero position.

EPU Resistance Chart
The document includes an EPU Resistance Chart for checking coil resistance at different voltages and temperatures. This is essential for diagnosing electrical issues with the pump.

Fittings And Machine Threads All fittings should be hand-tightened. An additional 1/8 - 1/4 turn after the fitting contacts the seal ring may be necessary to provide a leak-proof seal. Excessive overtightening or use of a pipe wrench can cause damage to the fittings, seals, or pump head. All LMI pumps have straight screw machine threads on the head and fittings and are sealed by the seal rings or O-rings. DO NOT use Teflon® tape or pipe dope to seal threads. Teflon® Tape may only be used on the 1/2" NPT thread side of the Injection Check Valve as well as stainless steel liquid end connections....

Electrical Connections To reduce the risk of electrical shock, install only on a circuit protected by a ground-fault circuit-interrupter (GFCI). The metering pump must be plugged into a grounded outlet with ratings conforming to the data on the pump control panel. The pump must be connected to a good ground. DO NOT USE ADAPTERS! All wiring must conform to local electrical codes. WARNING: Do not hook a US style pump plug into a non-US (UK, Aust, NZ or Swiss) wired power system. The US style 240VAC power system has two 110VAC hot legs and one neutral. The European style system has one 240VAC hot...

Flooded Suction The pump is mounted at the base of the storage tank. This installation is the most trouble-free , and is recommended for very low outputs, solutions that gasify, and high-viscosity solutions. Since the suction tubing is filled with solution, priming is accomplished quickly and the chance of losing prime is reduced. When pumping downhill or into low or no pressure system, a back pressure/anti-syphon device should be installed to prevent overpumping or syphoning. Although popular for all solutions, LMI recommends flooded suction installations for all high-viscosity fluid applications....
