Gunite Sprayer

Zhejiang Wengong Intelligent Technology Co., Ltd. is one of the leading manufacturers and suppliers of gunite sprayer in China. We are committed to providing high quality machinery with competitive price. If you're going to buy advanced gunite sprayer made in China, welcome to get quotation from our factory.

JP gunite sprayer are used in concrete 3D‑printing projects across China, USA, Australia and more. Manufacturers, research labs and construction contractors have given good real‑world feedback and market comments on these units.

Our company wanted full local supply for additive‑construction equipment. For this reason, we developed and manufactured the DJ2 concrete 3D‑printing extruder printhead at the same time. This item comes with national patent protection. When paired with JP‑series mortar pumps, it builds a full set for 3D‑printing material delivery and extrusion. Users can deploy it for lab R&D work, pre‑fabrication inside component factories, as well as additive construction right on building sites.

JP gunite sprayer are positive‑displacement screw pumps. They take charge of stable pressure delivery for special printing mortar. Output runs continuously with low pulse. Flow and pressure swing stay very small. There is no material dripping or unexpected feed cut‑off. Printed layers can keep consistent thickness. Both part forming accuracy and inter‑layer bonding performance get improved.

Users can pick either frequency‑conversion or mechanical speed control on this machine. Material flow can be adjusted steplessly, so material output can dynamically follow the moving speed of printhead.

JP gunite sprayer handles many tricky materials: fast‑setting sulfoaluminate printing mortar, geopolymer slurry, steel‑fiber reinforced high‑thixotropy printing concrete and so on. Rotor and stator inside pump core are reworked for better wear resistance, which fits slurries loaded with high‑content fillers.

Anti‑reverse rotation protection is built‑in. It copes well with frequent start‑stop and repeated inching adjustments, which are common during 3D‑printing work. Pump core parts are easy to take apart and put back together. Operators can quickly disassemble and clean them after shutdown, to avoid damage to wearing parts caused by solidified fast‑hardening materials.
