With an output temperature of 190 degrees F at 9 gpm, 690,000 Btu and a wet-stream option, Dynablast’s HV690F-12V hydrovac water heater is an ideal option for digging in colder climates. The unit also improves digging in clay-filled areas.
Like all other Dynablast models, the HV690F-12V comes with ETL certification for safety, which also includes certification on the coil for higher efficiency and heat transfer, along with a stainless steel target plate to increase coil life and momentary override control for better serviceability.
Water pump package
Dynablast also offers the Pratissoli KT28ASPF water pump package, which operates at 18.4 gpm at 2,900 psi and 1,450 rpm. It’s set up for hydrovac by reducing pump speed to lower water flow, resulting in increased pump life and reduced water bypass.
The package comes equipped with a T13 female spline shaft input and SAE B two- or four-bolt flange for direct mounting the hydraulic motor to reduce weight and space on the truck.
Other advantages of the Pratissoli KT28ASPF include a self-lubricating design; a manifold made of spherical nickel-coated cast iron with a 700 Brinell hardness rating; symmetrical crankcase so it’s easy to reverse shaft the pump; internal fins on an aluminum crankcase providing cooling to lower oil temperature; tapered roller bearing for improved lateral loading; two bore ceramic plungers thicker on the water end to prevent thermal shock; and longer run time between routine maintenance like oil changes.
Dynablast has manufactured hot-water equipment for more than 30 years and has worked 36 years as a national Canadian distributor for Interpump, Pratissoli pumps and PA products.
