Kemko® Model B Epoxy Injection Pump for concrete crack repair

The Model B is powered by 120 VAC (alternately can be fitted for 220-240 VAC) and designed to provide maintenance-free service for professional concrete crack repair using 2:1 ratio Kemko® epoxy injection resins. It features fail-safe shutoff sensors in case of an empty reservoir and all controls are solid state for extra reliability. Automatic pressure sensing solid state circuitry controls slow the flow of material as the preset pressure limit is approached thus avoiding surges. This epoxy injection pump meters two component epoxy resins within 2% accuracy and is designed to operate on its side in restricted spaces.

The Model B injection pump is available exclusively to Kemko® applicators who have attended a no charge training class focused on structural concrete repair. We manufacture and stock these crack injection pumps and all replacement parts in the U.S. for immediate shipment and maintenance. Note: this pump is designed for use with unfilled low viscosity 2:1 ratio epoxy injection resins only and will not work with filled or thickened epoxy gels or pastes (for latter application, see Model C). For useful application tips, see Epoxy Injection guideline specification and Introduction to Crack Injection.
