Product catalog summary
Overview: The document provides comprehensive details on Watson-Marlow's close-coupled pumps, including fixed speed, variable speed, and pneumatic models. It emphasizes the industrial applications and cost-effectiveness of continuous tubing and LoadSure™ elements.
Specifications: The pumps are available in various models with specific flow rates and speed options. The 701 series offers flow rates from 2 to 4,000 liters per hour, while the 621 and 521 series cater to different flow rate needs. Compatibility of different pumpheads with various drives is detailed for application flexibility.
Drive Options:
  • Varmeca Variable Speed Drives: Offer 10:1 speed control and constant torque, available in single-phase and three-phase models, with remote control and Profibus options.
  • Fixed Speed Drives: Available in three-phase models with various speed options.
  • Pneumatic Variable Speed Drives: Provide a 5:1 control ratio, requiring a filtered and lubricated air supply.
Pumphead Features:
  • 701R and 701RX: Feature continuous tubing and LoadSure™ elements, with flow rates up to 4,000 liters per hour.
  • 620R and 620RE: Include twin-roller pumpheads and LoadSure™ elements, with pressures up to 4 bar.
  • 520R2C and 520RELC: Offer high flow rates with continuous tubing and LoadSure™ elements.
ATEX Compliance: The document specifies ATEX directive compliance for pumps in potentially explosive environments, detailing Group II, Category 2 equipment for gas-based environments.
Tubing Technology: Watson-Marlow manufactures its own tubing, offering materials and sizes to optimize pump performance. Benefits of Marprene, GORE High Resilience Tubing, and STA-PURE PCS and PFL tubing are highlighted for their chemical resistance and durability.
LoadSure™ Elements: These elements ensure secure connections and easy installation, enhancing reliability and productivity. They are compatible with industrial-standard connectors for seamless system integration.
Material Specifications: FL is approved for USP Class VI and food grade, suitable for food, pharmaceuticals, and aggressive chemicals, operating from -20°C to 80°C. Neoprene performs well with abrasive slurries and sustained pressure applications, with a temperature range of 0°C to 80°C.
Pipework and Accessories: A variety of interface pipework is available for LoadSure™ element pumps, with options for industrial valved or non-valved connectors. Leak detection sensors are available for most pump ranges.
Cost Savings on Tubing: Tubes are available in bulk, offering significant cost savings of 36% per meter compared to shorter lengths, with further discounts for multiple reel orders.
Pumpsil Tubing: Pumpsil platinum-cured silicone tubing is manufactured in an ISO1644-1 class 7 cleanroom for biopharmaceutical applications. It is USP Class VI and ISO10993 certified, FDA compliant, and free of leachables, featuring an ultra-smooth bore to control protein binding and bacterial growth, with a working temperature range of -20°C to 80°C. It is autoclavable and features LaserTraceability™ for traceability.
Company Information: Watson-Marlow Pumps Group operates five factories and has sales operations in 20 countries, with distributors in over 50 countries. More information and brochures are available on their website.
