GTB-970 Elastomeric Coating Sprayer: 15.0 L/min Hydraulic
Heavy-Duty 15.0 L/min Elastomeric Coating Sprayer Engineered for Ultra-Thick Roofing Projects
Engineered for the most demanding heavy-industrial applications, the GTB-970 High-Production unit is a severe-duty hydraulic airless sprayer that delivers a massive 15.0 L/min flow rate. Powered by a 4000W 380V 3-phase electric motor (or a 9HP gas engine), this hydraulic beast effortlessly pushes ultra-high-viscosity materials—including elastomeric coatings, fibered asphalt emulsions, and 100% solid epoxies—while flawlessly supporting up to a 0.055″ tip. Built around a USA Haas CNC-machined fluid pump holding ±0.01mm tolerances and validated by Zeiss CMM Inspection, it houses Heavy-Duty UPE & Leather Composite V-Packings and a Tungsten Carbide Valve Seat to withstand relentless abrasion. This is the operational baseline for immense roofing projects and commercial waterproofing environments.

Industrial Hydraulic Technology
Unstoppable Hydraulic Performance Engineered for Ultra-High Viscosity Protective Coatings
Relentless hydraulic piston delivery generating 15.0 L/min at a continuous 3000 PSI, featuring a USA Haas CNC-machined fluid pump loaded with Heavy-Duty UPE & Leather Composite V-Packings for unstoppable industrial output.
Advanced Thermal Dissipation for Non-Stop Operation
Faster Cooling & No DowntimeEngineered for absolute thermal stability, the advanced hydraulic cooling reservoir dissipates heat instantly during relentless continuous operation at 3000 PSI. Eliminating downtime risks in brutal environments, the entire thermal and mechanical architecture maintains strict EN ISO 12100:2010 compliance, guaranteeing safe, uninterrupted peak performance on extreme industrial job sites.
Anti-Cavitation Severe-Duty Hardened Fluid Pump
Unrestricted High-Viscosity FlowThe submerged foot valve and direct immersion fluid section forcefully load ultra-heavy materials without cavitation. Fortified with a Tungsten Carbide Valve Seat and Heavy-Duty UPE & Leather Composite V-Packings, this pump withstands brutal abrasion. The resulting 15.0 L/min throughput guarantees superior atomization of thick elastomeric and fibered asphalt compounds.
High-Output Dual Power & 100% Factory Validation
MAXIMUM POWER TRANSFERFeaturing rapid, tool-less power conversion between the 9HP gas engine and the industrial 380V 4000W 3-phase electric motor, this rig adapts instantly to any site requirement. Guaranteeing uncompromising factory reliability, every sprayer is factory tested with a 30-minute high-pressure load test before deployment to ensure absolute structural integrity.
Material Compatibility of this 15.0 L/min Elastomeric Coating Sprayer
A relentless industrial workhorse engineered specifically to dominate high-volume waterproofing and maximum-yield protective coating infrastructure.
Supported Materials
✅ Heavy Elastomeric Coatings
✅ Fibered Asphalt Emulsion
✅ 100% Solid Epoxies
✅ Acrylic Waterproofing
Not Recommended
❌ Cementitious Mortar with Aggregates (Will permanently destroy fluid section)
❌ Plaster / Stucco
💡 Factory Pro Tip:
Leveraging the massive 15.0 L/min flow rate and the oversized 0.055″ tip is critical when spraying highly viscous Elastomeric Coating; it reduces clogging and maximizes yield.
Internal Engineering
Why Choose the GTB-970 High-Production Airless Sprayer
Built for extreme industrial elastomeric and heavy-duty roof coatings. The absolute operational baseline for large-scale waterproofing production.
When standard high-pressure fails, this 6000 PSI ultra-high-pressure juggernaut takes over. Specifically forged to blast through high-resistance 100% solid epoxies and thick intumescent fireproofing, it deliberately sacrifices broad-area output for absolute material penetration. Every precision part is machined on USA Haas CNC centers and survives a punishing 30-minute factory load test. It is the ultimate heavy-duty weapon for marine, shipyard, and severe steel structure protection.
Reinforced Transmission System
Engineered with a severely reinforced hydraulic mechanical structure to easily withstand the massive 6000 PSI (40 MPa) internal forces, translating raw engine torque into relentless spraying power.
Unyielding Thermal Stability
Driven by an industrial 4000W motor or 9HP engine. It features aggressive heat dissipation capabilities to prevent thermal shutdown even when operating at extreme 6000 PSI load conditions.
Anti-Cavitation Fluid Dynamics
Equipped with a wear-resistant Tungsten Carbide Valve Seat and heavy-duty UPE packings. The 7.5 L/min pump is meticulously designed to prevent cavitation when siphoning stubborn, ultra-thick epoxies.
