PQE GRC spray gun is professional spraying equipment built for high‑viscosity polymer fiber mortar applications. It is widely used in many construction projects, including manhole rehabilitation, trenchless polyurea‑mortar composite construction and wall plaster reinforcement.

PQE GRC spray gun is made to handle special polymer mortar mixes with chopped‑fiber additives. Common problems found on traditional spray guns, such as frequent blockages, uneven fiber distribution and high material rebound rates, can be solved with this unit. Its internal flow path adopts a large‑bore streamlined anti‑clog structure for good material compatibility. Users can feed polymer mortar mixed with polypropylene, polyethylene and other chopped fibers directly through the gun, without extra water dilution. Fibers will not get tangled or accumulated inside the gun chamber. Material can flow continuously and stably throughout spraying work, avoiding common operating faults like discontinuous feeding and mortar spattering.

The spray gun supports multiple spray modes including fan‑shaped and cylindrical jets, which operators can switch quickly for different site construction needs. Spray width can be adjusted continuously between 200‑600 mm, helping to achieve even fiber distribution on wall surfaces and prevent layered material build‑up. Single‑pass spray thickness can reach up to 30 mm, and rebound rate remains below 5%, which effectively cuts material loss.

We adopt long‑life design principles and keep routine maintenance simple for this spray gun. Tungsten‑steel wear‑resistant bushings serve as core flow‑passing components, so the spray gun can work reliably even for abrasive polymer mortar mixes containing quartz sand. A quick‑release structure is fitted on the gun body. Operators can take apart and clean the gun chamber within three minutes, and no special tools are required for daily maintenance work.

Ergonomic design makes this spray gun fit various construction scenarios. At only 1.2 kg, it greatly reduces hand fatigue for workers during long‑time handheld operations, whether working at height or inside manholes. A standard quick‑connect fitting comes pre‑installed on the gun. It can connect directly with most JP‑series mortar spraying units available on the market. No modification is needed for existing equipment or piping, and users can start operation right away.

As a key component for polymer‑fiber‑mortar special construction work, the spray gun greatly improves mortar surface finish and overall construction efficiency. It delivers optimal performance when used together with the manhole‑chamber polymer‑mortar polyurea‑bonded spraying process, jointly developed by Wenzhou Institute of Technology.
