Pulsafeeder NC91XA6LP1-XXXX Head and Roller Assembly
The Pulsafeeder NC91XA6LP1-XXXX is a genuine head and roller assembly for Chem-Tech Series XP and XPV peristaltic metering pumps, the complete pump head that the squeeze tube runs in, together with the rotor and rollers that drive the chemical through it. The part number identifies it for the size 6 tube, low pressure configuration, and it replaces the head as a unit rather than rebuilding individual rollers.
Replace the head and roller assembly when the rollers are worn, sticking or noisy, when the head housing is cracked, or when chemical from a split tube has attacked the rotor. A worn rotor wears new tubes out quickly, so replacing the head at the same time as the tube is often the most economical repair. The correct head assembly varies by model, so check the pump model and tube size on the data label before ordering.

Frequently Asked Questions
Q: Is a tube included?
Fit a new size 6 tube assembly with a new head. Running an old, set tube in a new head gives neither part a fair start.
Q: How is the head removed?
Remove the front cover thumb screws, take out the tube assembly by releasing both connector fittings, then pull the rotor straight out of the head.
Q: Do the rollers need service?
The roller bearings benefit from periodic lubrication. Rollers that are dry, flat spotted or seized mean it is time for a new assembly.
Q: Will a head from a high pressure pump fit?
The mounting is common, but high and low pressure heads are matched to their tubes. Keep to the configuration shown on your pump label.
