Masterflex 7550-90 pump drive with 7518-00 Easy-Load head

  • Max speed: 600 rpm
  • 90-day warranty

The Masterflex 7550-90 pump drive is part of the Masterflex L/S series, designed for precise fluid transfer applications. It features three rollers and can operate at a maximum speed of 600 RPM. The housing materials include options like polysulfone (PSF), polyphenylene sulfide (PPS), stainless steel (SS), anodized aluminum, and nylon. Using MASTERFLEX precision tubing is recommended for optimal performance.

The 7518-00 Easy-Load pump head is compatible with the Masterflex L/S drives. It offers automatic tubing retention, allowing easy setup without manual adjustments. The pump head accommodates multiple tubing sizes and features a four-roller rotor for improved pressure performance and reduced pulsation. Users can change tubing without removing the head from the drive, making it a versatile choice for fluid handling applications.

This pump is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
