Pulsafeeder NC90XX2HPA-XXXXX Tube Assembly
The Pulsafeeder NC90XX2HPA-XXXXX is the genuine size 2 high pressure pump tube assembly for Chem-Tech Series XP and XPV peristaltic metering pumps. It is the squeeze tube that the rollers work against, supplied as a complete assembly with its nut, sleeve, clamps and fittings for 1/4 in OD suction and discharge tubing, so it can be fitted without cutting or clamping loose tubing.
In a peristaltic pump the tube is the only part the chemical touches, and it is the main wear item. As it fatigues it loses its round shape, output falls, and eventually it splits. The size 2 high pressure tube suits the lowest flow Chem-Tech XP and XPV models, including the 4 and 7 GPD XP pumps and the 8 GPD XPV. Replacing the tube on a schedule, rather than waiting for a split, keeps output steady and chemical off the pump.

Frequently Asked Questions
Q: How often should the tube be changed?
It depends on hours of running and discharge pressure. Many operators change it at a fixed interval, and a new tube ships with each new pump as the first spare.
Q: Do the rollers need lubrication when fitting a new tube?
Yes. Lightly lubricating the tube where the rollers run extends its life, and the roller bearings benefit from periodic lubrication as well.
Q: Can I fit a low pressure tube instead?
Only if the pump was specified for low pressure. The high pressure tube has a heavier wall for pumps feeding against higher line pressure.
Q: What causes early tube failure?
Running against a closed or blocked discharge, abrasive solids in the chemical, or a chemical the tube material is not rated for.
