Key Details

The 16U798 cylinder is engineered for high-pressure pumping systems that require durable, precisely machined fluid-section components. When replacing this part, ensure that your machine uses the matching pump lower layout, connection fittings, stroke length, and pressure specifications.

Important Usage Notes

This pump cylinder is not universal. Installing the incorrect cylinder in a non-supported pump may cause reduced performance, leakage, or mechanical damage. Always verify machine compatibility and pump-lower model before installation.

Frequently Asked Questions

Systems using this pump cylinder are typically designed for cementitious materials, mortars, spray-applied fireproofing, and other heavy-viscosity coatings.

When installed in the correct pump lower assembly, systems with this cylinder can typically operate up to high-pressure ranges suitable for mortar and fireproofing materials. Actual working pressure depends on the specific ToughTek model.

No. The 16U798 is designed for specific ToughTek systems only and must match pump-lower configuration, inlet/outlet size, mechanical alignment, and pressure requirements.
