Concrete Pumps

By: Canusa Equipment  09-12-2011

A Series “Rockmaster” pumps are economical 30 or 40 cubic yard per hour concrete pumps, capable of pumping harsh pea gravel mixes all the way up to “big rock” concrete. A Series Pumps offer the best values on the market for their horsepower, pressure, and volume combinations.

- “True Reverse”; if your line plugs, the pump’s S-valve can reverse the flow of concrete in the line to relieve the pressure. This can dislodge rock jams quickly and safely (ball valve pumps cannot do this!)

- Heavy duty 5″ x 5″ S-valve; this valve gives the Rockmaster the ability to pump the harshest pea gravel mixes all the way up to 1″ (25mm) hard rock concrete. (Ball valve pumps are restricted to pea gravel mixes.)

- 82hp (61kW) Perkins diesel engine; this best-in-class horsepower gives the Rockmaster the ability to handle a wide variety of pumping applications: commercial slabs and decks, shotcrete, residential work and more. The Rockmaster is capable of doing the same job as pumps that cost almost twice as much!

- REED’s Exclusive can-bus solid state electric system; The Rockmaster’s robust electric system delivers trouble-free long term results

- Chromed concrete cylinders; deliver longer service life than standard steel cylinders

- 29 Gallon (110 Liter) fuel tank; the A30′s large fuel tank means more pumping without refueling

- REED “1-3-2 Warranty”: Covers parts for one year, structural for three years, and the Black Box for two years.
