KP-1403A Gear Pump

The KP-1403A gear pump is pretty much a staple if you're running medium dump trucks and need something reliable for the tipping and lifting side of things. It does a great job of keeping the fluid flow steady under pressure, so the truck bed actually goes up and down smoothly without that annoying, jerky stuttering you get with cheaper pumps.Instead of making you mount a bunch of extra valves all over the frame, we built the control functions right into the pump housing itself. That makes the installation way less of a headache and cuts down on the extra plumbing. It's put together with tough castings and solid internals, so it doesn't mind the dust, mud, or rough handling out on a job site. You'll usually see these running on construction trucks and haulers where people just want a dependable hydraulic setup that won't leave them broken down or constantly spinning wrenches in the shop.

Advantages of the KP Series Unloader System

1. Smooth, Fuss-Free Hydraulic Control

The built-in valve stops leaks before they start. Packing the control valve right inside the pump body keeps the plumbing simple. It cuts down on extra joints and lines, which gives you a tight system with fewer places for fluid to leak out when tipping the truck bed.

Fewer mistakes on the job. Having a highly responsive setup means you don't have to fight the levers, making your dump truck runs way more efficient.

2. Durable and Reliable Design

Manufactured with high-quality materials, the system is built to withstand heavy-duty applications. It ensures long-term durability and consistent performance, even in challenging work environments and demanding tasks.

Saves you cash on upkeep. Because the parts don't wear down early, you aren't stuck dealing with constant maintenance or unexpected downtime, which keeps your trucks out on the road making money.

3. Put Together for Heavy Hauls

Gives 4-10 ton trucks the muscle they need. This setup provides plenty of hydraulic push to handle heavy tipping loads across construction, mining, or hauling jobs.

Stays stable under pressure. It won't bog down or stutter when the working conditions get punishing, giving you reliable performance every time you trip the bed.

Features of the KP Series Unloader System

1. All-in-One Pump and Valve Layout

Clears out the clutter under the chassis. Having the control valve integrated directly into the pump streamlines your entire hydraulic layout, reducing overall complexity.

Saves valuable frame space. Since you don't have to mount separate components, installation is a whole lot faster and it frees up room for other gear.

2. Accurate Bed Positioning

Smooth lifting and lowering cycles. The control valve lets you make tiny, precise adjustments instead of the bed jerking up and down, keeping loading zones much safer.

Intuitive handle feedback. Operators can easily feel out the system's response, allowing them to drop or hold the tipping bed exactly where they need it.

3. Ready to Mount on Most Medium Tippers

Fits standard 4-10 ton truck specs. The design is highly adaptable for mid-sized haulers working in construction, mining, or moving agricultural loads.

Bolts up without major modifications. The versatile frame setup makes it easy to adapt to different truck models and configurations without a headache.

4. High-Pressure Tolerance

Engineered for intensive cycles. The internals are built to handle serious hydraulic pressures, making it an excellent match for harsh environments like quarries or waste management yards.

Gives you extra overhead for tough jobs. This pressure handling means the system can stay in service longer without failing when pushed hard day after day.
