Western Grater uses various types of grout mixers and pumps, including: DSI MP 2000 mixer-pumps, which are colloidal mixing units combined with Moyno progressive cavity pumps; and, Obermann VS-63-20 F/G mixer-pumps, which are digitally controlled high pressure mixer-pumps for technically critical applications.   Our pumps are suitable for a multitude of grout and concrete mixes, and we have the tooling required for accurate placement of those mixes in unfavorable conditions.
