HZ-30G/D Overview


This pump is a triple threat. It comes in three configurations — Towable Axle, Narrow Axle and Truck Mounted. This is basically the gas version of the 30E, and it’s great for manhole renovations, hard-coat stucco spraying and more.

The 30G is highly popular among stucco applicators but also appreciated by contractors all across the coatings industry. Marquis Construction Services, Inc. says it can spray as many as 30 truckloads of fireproofing material with this pump. “The machine still has all the original wear parts and it’s still pumping great,” said Marquis’ construction manager David Wilson.

High Output* or High Torque**

✝ 1 bag = 3.0 cu ft yield
* High output model recommended for use with products that pump more easily where higher output is desired. Low-density fireproofing and self-leveling underlayments would be good choices.
** High torque model recommended for use with hard-to-pump products or extreme pumping distances or heights. Mortars and stuccos would fit this category.
*** This is maximum largest aggregate size recommended for pump. Mix design will determine how effectively the product will pump.
**** Pumping distance and output may be increased or decreased significantly depending on mix design, but we believe these to be very achievable in most instances.
