Product Overview
The 3CBL-FC Series - Triple Gear Pump puts three single gear pumps in one housing. Each section has its own inlet and outlet. Three independent flows from one drive shaft.
Why put three in one? Saves space. Saves cost. Keeps things simple. You get three separate hydraulic supplies without mounting three separate pumps. No extra couplings. No extra brackets. No extra headaches.
The layout is straightforward. Three gear sets share a common shaft. Each section pulls oil from its own inlet and pushes it out its own outlet. The flows stay separate. They do not mix.
Gear pumps are about as simple as it gets. Two gears mesh. Oil gets trapped between the teeth and the housing. It moves from inlet to outlet. That is the whole story. Few moving parts. No valves. No pistons. No complex controls. Just two gears spinning.
The 3CBL-FC takes pressure spikes in stride. Gear pumps tolerate shock loads better than piston pumps. If your system sees sudden load changes, this pump handles them.
One section fails, the other two keep running. You replace one section, not the whole pump. That is the beauty of independence.
Product Features
Three independent flows. One pump, three circuits. Each section pulls from its own inlet and delivers to its own outlet. The flows do not mix. No compromises.
Simple design. Gear pumps are straightforward. Two gears, a housing, and a shaft. That is it. Fewer parts than piston pumps. Less to break. Less to fix.
Shock load tolerant. Pressure spikes happen. Gear pumps handle them better than most. Built for tough conditions.
Independent sections. One section goes down, the other two keep running. You fix one section, not the whole pump.
Compact package. Three pumps in one housing. Less space. Less installation time. Fewer brackets and couplings.
Multiple configurations. Mix and match displacements. Standard combinations available. Custom ones on request. Tell us what you need.

Where You Use These Pumps
The 3CBL-FC is built for systems that need multiple independent flows.
Industrial machinery. Machine tools. Presses. Test stands. Each circuit gets its own oil supply.
Construction equipment. Excavators. Loaders. Cranes. One pump runs several functions at once.
Lifting gear. Hoists. Lifts. Cranes. Different motions need different flows. The 3CBL-FC provides them.
Mining equipment. Conveyor drives. Crushers. Reliable power in tough conditions.
Mobile equipment. Agricultural machines. Utility vehicles. Multiple circuits from one compact unit.
Need three separate hydraulic supplies? This pump delivers them in one package. No extra pumps. No extra mounting. Just three flows from one drive shaft.
Installation
Mounting. Oval or square flange. Standard options.
Shaft end. Plain key or rectangle spline. Match your drive coupling.
Rotation. Left or right. Specify when ordering.
Port connections. Three inlets and three outlets. Standard threads. Connect your lines.
Mounting orientation. Install with ports facing accessible direction. Consider service access.
How We Build These Pumps
Casting
Iron castings arrive. We check for defects. Good ones move to machining.
Machining
The housing is machined. Gear bores are bored to size. Ports are drilled. Mounting faces are machined flat.
Gear grinding
Gear teeth are ground. Surface finish and profile are checked. Clearances are held tight. Efficiency depends on these clearances.
Assembly
Three gear sets are installed. Shafts are fitted. End covers are bolted on. All fasteners are torqued.
Testing
Every pump goes on the test stand. We check flow at rated speed. We check pressure rise. We check efficiency. Volumetric efficiency must meet 90% minimum.
Every 3CBL-FC Series - Triple Gear Pump goes through the same rigorous testing before it leaves our facility.
Painting
The housing gets industrial paint. Mounting surfaces stay bare.
Packing
Cartons for small orders. Plywood cases for bulk. Test reports included.
Shipping
Sea, air, rail, truck, or express. We ship worldwide.
About the Company
We started in 1988. Over 35 years in hydraulic components. Our team has more than 200 people. Some have been here twenty years. They know the product inside out.
We are a factory. Not a middleman. We machine the parts. We assemble them. We test them. Everything under one roof. That gives us control.
We ship over 10,000 containers a year. Customers in more than 20 countries-Russia, Europe, the Middle East, South America, Southeast Asia. Our pumps run on agricultural equipment in Poland, construction machines in Chile, press lines in Thailand, and mining gear in South Africa.
Quality
We do not spot-check. Every batch goes through at least 10 inspections. Each pump gets tested on its own stand. Flow, pressure, efficiency-we verify everything.
Engineering
We have real engineers on staff. Not just salespeople reading spec sheets. Senior industry experts advise us. Our team keeps pushing the product forward.
What you get
12-month warranty from Bill of Lading date. Support from people who know hydraulics. Shipping by sea, air, rail, truck, or express-whatever works for you. Export packaging that holds up.
FAQ
Q: What is a triple gear pump?
A: Three single pumps in one housing. Each section has its own inlet and outlet. Three independent flows from one pump.
Q: What are the main advantages?
A: Simple construction. Reliable. Easy to maintain. Handles shock loads. Three flows in one compact unit.
Q: What is the difference between a triple gear pump and three separate gear pumps?
A: A triple gear pump combines three pumps in one housing with a common drive shaft. Three separate pumps need three couplings, three mounting brackets, and more space. The 3CBL-FC saves space, cost, and installation time.
Q: Can the three sections operate at different pressures?
A: Yes. Each section has its own outlet and can operate at different pressures. The sections are independent. Pressure in one section does not affect the others.
Q: What happens if one section fails?
A: The other two sections keep working. Each section is independent. You can replace one section without replacing the whole pump.
Q: What is the recommended oil viscosity?
A: Use anti-wear hydraulic oil with viscosity of 32 to 68 cSt at operating temperature. Higher viscosity oils may cause cavitation. Lower viscosity oils increase internal leakage.
Q: What is the typical service life of the pump?
A: Depends on oil cleanliness and operating conditions. With clean oil and proper maintenance, the pump runs for many years. Contamination is the main cause of premature wear.
Q: Can the pump be repaired in the field?
A: Seal replacement and port cleaning can be done in the field. Major repairs require clean room conditions. Ship it back to us for major work.
