DESCRIPTION
LTC Series Liquid Pumps are offered in both brush and brushless DC motor drives that can be configured for your specific performance requirements. These pumps are designed to handle a wide range of liquid and gas media.
DYNAMIC BENEFITS
  • Fluid-Blok™ Advanced Sealing Technology**: Redundant sealing techniques eliminate leaks.
  • Self-Priming/Dry Running: Monolithic diaphragm design allows for maximum suction/priming and continuous dry operation.
  • Longevity: Unique brushless DC motor design and advanced proprietary diaphragm elastomer gives the highest benchmark for service-free life.
  • Low Power Consumption: Advanced flow path and efficient valve system design** allows for maximum flow with low power consumption.
  • Port Design: Port design allows for top or bottom face seal and is molded for 1/4-28 UNF threaded fittings, as well as four head configurations.
  • Chemical Resistant: Structured to be inert to a variety of media with selected wetted components.
  • Light Weight, Compact Size: Compact configuration allowing designers to minimize system weight and space requirements.
  • Flexible Mounting Options: Maximizes mounting flexibility by offering several mounting options.
  • FDA-Approved Materials: Hargraves pumps and compressors are commonly used in FDA-approved systems.
OVERALL PERFORMANCE RANGE
Above performance ranges illustrate overall performance for all LTC pumps handling water at room temperature. Performance will vary depending on barometric pressure, media temperature, density, and viscosity.
