Its advanced design optimizes fuel flow while reducing installation complexity and long-term maintenance requirements. The pump is supported by Veeder-Root’s global network of distributors and authorized service contractors, ensuring dependable lifecycle support.
Technical Specifications (1.5 HP – 50 Hz)
This submersible centrifugal turbine pump is designed for reliable, continuous-duty operation in demanding fuel applications. It features a standard 4-inch threaded tank opening for easy installation and a robust 1.5 HP (1.13 kW) single-phase motor running at 2850 RPM on a 220/240 V, 50 Hz supply.
Built for safety and durability, the pump is explosion-proof (Class I, Group D) and includes built-in automatic thermal overload protection to prevent motor damage. Its multi-stage, self-lubricating centrifugal design ensures efficient pumping with a 2-inch NPT discharge outlet.
Engineered to perform in challenging environments, it operates reliably within an ambient temperature range of -20°C to +51°C and handles product temperatures up to 40.5°C. The pump meets stringent safety and performance standards, certified by UL 79 and cUL approvals.
Mechanical & Design Features
The 4” Red Jacket STP uses a multi-stage impeller and diffuser system to deliver stable pressure and high flow efficiency. Impellers are splined to the pump shaft to ensure positive, non-slip rotation, while diffusers are securely fixed to prevent movement and wear.
A horizontal pump intake minimizes sediment pickup from the tank bottom, protecting internal components and improving longevity. The pump and motor assembly can be removed as a unit from above ground, allowing fast servicing without disconnecting discharge piping, leak detection systems, or siphon equipment.
The extractable packer manifold head assembly provides a complete seal against fuel leakage and water intrusion. It integrates key safety components including:
The Lock-n-Lift check valve system allows controlled depressurization of the line during servicing, safely returning fuel to the tank and preventing spills.
Electrical Features
The pump is powered by a hermetically sealed, explosion-proof electric motor designed for hazardous fuel environments. The motor includes:
Electrical disconnection is automatically achieved when the extractable packer assembly is removed, eliminating the need for swing joints or manual wiring disconnections.
Types & Configurations
The 4” Red Jacket STP is available in Quick Set® adjustable length configurations, allowing one pump model to fit multiple tank depths. Lengths are adjustable on-site and can be resized in the future without replacing the pump assembly.
Configurations are available:
This flexibility significantly reduces inventory requirements and installation time.
Fuel Compatibility
The Red Jacket 4” STP is UL-listed and approved for use with:
Fuel compatibility ensures suitability for both conventional fuels and commonly used blended fuels.
