Excalibur Hydra Mobile Plaster Pump

Excalibur Hydra SR-2

The Spray Force Excalibur Hydra is revolutionizing the plaster pumping industry. Stemming from the industry's leading plaster pump, the Excalibur, the Excalibur Hydra is the first and ONLY completely hydraulic plaster pump on the market. With its groundbreaking design, the Excalibur Hydra offers a number of improvements over a traditional plaster pump.

The Excalibur Hydra uses one 37HP diesel power plant for both the pump & mixer. The Excalibur Hydra uses an Automatic Self-Compensating "Smart System" to automatically adjust hydraulic oil flow to save fuel and reduce equipment wear & tear. The equipment uses a high efficiency oil system to power the hydraulics and reduce maintenance costs. The equipment has fingertip speed control for both pump and mixer located on the side of the unit over an infinite operating range. No more manual changing of gears as speed change is as simple as a turn of the dial. With a completely hydraulic system, the equipment maintains maximum horsepower throughout various RPM levels giving you the ability to pump and mix even the toughest materials. A full spout Powermix 1010 mixer with right-hand dump is utilized to eliminate splash and reduce jobsite cleanup.

The Excalibur Hydra, with its infinite speed range, is capable of pumping the thickest scratch & brown, fireproofing material, EIFS, dash, sand/cement slurries, and even color stucco finish. The Excalibur Hydra is changing the way plaster contractors work.
