|Blastcrete Equipment Co.'s D3522 Attachment hot epoxy pump.|
The D3522 Attachment from Blastcrete Equipment Co. features a hydraulic squeeze (peristaltic) pump that is built for long life and low total cost of ownership, according to the company.
The pump has two rollers that rotate clockwise and squeeze a 2-inch rubber pumping tube. The rotation generates suction from the receiving hopper and pushes the material through the pump and out the discharge into the delivery hose. The epoxy materials do not come in contact with the moving parts of the squeeze pump, unlike a rotor stator or piston-style pump. According to the company, the D3522 Attachment’s primary wear part, a 2-inch rubber pumping tube, can be replaced in 20 minutes or less.
