LMI PD061-848SI PD Series Manual Adjustable – 48 GPD 70 PSI – 115V

The LMI Series PD Metering Pump is a versatile, high-performance chemical metering pump designed for precise and reliable chemical injection in various industrial applications. Below is an overview based on the detailed specifications you’ve provided:

Key Features:

• Flow Rate & Pressure:

  • Flow Rate: 2 GPH (Gallons Per Hour)

  • Pressure: 70 PSI (Pounds Per Square Inch)

• Power Supply:

  • Voltage: 115 VAC (Volts Alternating Current)

  • Frequency: 50/60 Hz

  • Plug: US Plug

• Pump Type:

  • Positive Displacement (Liquifram type)

Manual Control:

• The pump features manual control of the stroke frequency (also referred to as stroking rate), adjustable via a split-scale dial. This dial ensures precision even at lower flow rates.

• Stroke length is fixed to maintain consistent calibration across the adjustable flow range.

Key Components:

1. Molded FastPrime Head & Double Ball Check Valves:

   • These components contribute to the pump’s durability and functionality, ensuring smooth operation and quick priming.

2. 4-Function Discharge Valve Accessory:

   • The discharge valve allows for better control over flow and pressure.

   • Pressure Relief: The LMI 4-Function Valve helps automatically relieve pressure when combined with a FastPrime or AutoPrime liquid end.

Design and Build:

• Pump Housing:

  • Constructed with NEMA 4X/IP 65 ratings, making it highly durable and suitable for harsh environmental conditions, including outdoor use.

• Drive Assembly:

  • The drive assembly is fully enclosed with no exposed moving parts, enhancing safety and durability.

  • Electronics are housed in a chemical-resistant enclosure at the rear for protection against spills.

Liquid End Features:

• FastPrime Liquid End:

  • Ensures fast and easy priming with an integrated bleed valve, ideal for quick startups and maintenance.

• AutoPrime Liquid End:

  • Specifically designed for handling off-gassing liquids, ensuring that the pump operates smoothly without airlock issues.

Materials of Construction:

• Valve seat and seal ring are renewable by replacing the seat-seal ring or the cartridge valve assembly, reducing maintenance costs and downtime.

Tubing and Connections:

• Tubing: Includes 16 feet (4.8 m) of tubing, with compression connections provided on models with tubing connections.

• Foot Valve & Strainer: A foot valve with an integral one-piece strainer is provided for suction lines (on non-high viscosity models).

• Injection Check Valve: Features a 1/2″ NPT male connection for the injection point, ensuring proper flow and back pressure management.

This pump is designed for industries requiring precise chemical dosing, including water treatment, chemical processing, and other sectors that need reliable and adjustable chemical metering pumps.
