Large 3-plunger High-pressure Pump

 

Small pumps struggle with thick paint and hard rust. So we built a larger one. This Large 3-Plunger High-Pressure Pump is for big jobs. We made the plungers thicker. We increased the flow. The result is a pump that cleans large ship bottoms fast. It strips away 10-year-old paint in one pass. We tested this machine in our own shipyard before we sold it to anyone. It passed every test.

These numbers come from real work, not a lab. The 40 L/min flow means you cover more area faster. The 2800 bar pressure blasts away rust down to bare metal. Use it for docks, decks, steel structures, or ship bottoms. Our team of 30+ workers assembles each pump with care. We have a separate quality engineering department. They check every component before assembly.

 

 

Our company started as Tongda Anticorrosion. We worked in ship repair for 30 years. In 2024, we renamed to Qingdao Aobot and set up a new factory for rust removal equipment. So we are not new to this business. We know what customers need because we were customers ourselves. This Large 3-Plunger High-Pressure Pump comes from that experience. Every design change came from a real problem we saw in the field.

 

 What makes it reliable:

• 100% full inspection before delivery
• One-year warranty on the whole machine
• After-sales online response within 2 hours
• Spare parts ready in our warehouse

We also have our own R&D team. They cover mechanical, hydraulic, electrical, and high-pressure fluid. We do not outsource the brain of the machine. We build it ourselves.
