Kemko® Model B Epoxy Injection Pump for concrete crack repair

Kemko Model B epoxy injection pump

The Kemko® Model B Epoxy Injection Pump 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 and helping prevent blow-outs of the crack seal.

The Model B epoxy injection pump is positive displacement and precisely meters two component epoxy resins within 2% accuracy and is designed to operate both vertically and on its side in restricted spaces. The Model B external case is anodized aluminum for light weight and corrosion protection. The Model B has received the CE marking for approved use in all EU countries.

The Model B injection pump is available exclusively to Kemko® applicators who have attended a no-charge training class provided by ChemCo Systems focused on structural concrete repair and epoxy installation procedures. We manufacture and stock these crack injection pumps and all replacement parts in the U.S. for immediate shipment and maintenance. Note: the Model B 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 the latter application, see Model C paste pump). For useful application tips, see our Epoxy Injection guideline specification and Introduction to Crack Injection slides.
