Stainless Steel Self-Priming Jet Pump – Horizontal Multistage Booster Pump
Product Overview
Our Stainless Steel Self-Priming Jet Pumps are high-efficiency, horizontal multistage units engineered to deliver reliable, high-pressure water across a wide range of demanding applications. Built with a premium, rust-free Stainless Steel AISI 304 pump body, these compact units are perfect for transferring clean water, pressurizing home supply lines, and managing water treatment systems. Thanks to its advanced self-priming jet design, this pump effortlessly draws water even if air is present in the suction line, making it a dependable, low-maintenance solution for modern plumbing systems.
Key Features & Benefits
Rust-Free Hygiene: Complete Stainless Steel AISI 304 pump body and mechanical seal housing ensure drinking water remains perfectly clean, safe, and free from rust contamination.
Advanced Self-Priming: Automatically clears air from the suction line to prime itself quickly, preventing airlocks and minimizing manual intervention during startup.
Durable Internal Components: Equipped with high-grade S.S. 304 / Noryl® impellers and a strong Stainless Steel AISI 303 motor shaft to ensure maximum wear resistance and quiet performance.
Reliable Leak Protection: Fitted with a premium Ceramic-graphite-EPDM mechanical seal that stands up to high operational pressures without weeping.
Lightweight & Efficient Heat Dissipation: Designed with a rugged, compact aluminum motor body that sheds heat rapidly during continuous, heavy-duty run cycles.

1. Choosing the Right Model for Your Home
HTJET 370 (0.5 HP): Perfect for small homes, single-floor pressure boosting, or feeding small water purification setups.
HTJET 750 (1.0 HP) & HTJET 1100 (1.5 HP): Designed for multi-story residential buildings, long-distance pipeline transfers, and high-pressure commercial RO systems requiring up to 4,800 Liters per Hour.
2. The Self-Priming Advantage
Traditional centrifugal pumps require the suction pipe to be completely free of air pockets to work. Our HTJET series utilizes a built-in venturi jet mechanism that pulls air out of the line and creates a strong vacuum. This makes it highly effective for pulling water from underground sumps where minor line air leaks are common.
3. Installation Tips for Best Performance
Initial Priming: While the pump is self-priming, you must fill the pump casing with water through the top priming plug before turning it on for the very first time. Running it entirely dry will ruin the ceramic mechanical seal.
Foot Valve Recommendation: For deep underground sumps, always install a quality foot valve at the bottom of your suction pipe. This keeps the water column intact and allows the pump to deliver water instantly the moment it turns on.
