Watson-Marlow Bredel: Compact Metering Pumps
This company offers its 500 Series of pumps for adhesive-metering applications. The pumps reduce maintenance downtime, resist damage from corrosive chemicals and viscous slurries, and maintain a high standard of repeatability and accuracy. By allowing the slurries to contact only the inner wall of the tube, the pumps prevent corrosion and wear. In addition to offering a reversible option for back-flushing lines, the 500 Series is self-priming, self-checking and can run dry indefinitely. The pump head accepts tubing in seven different sizes and six materials. Extremely durable, the pumps accommodate flow rates of 1.152 gal/min and can withstand pressures up to 30 psi.
