How Do You Identify the Right Hydraulic Main Pumps for Replacement?

What Are the Core Responsibilities of Hydraulic Main Pumps?

Hydraulic main pumps are the stars of machines like excavators. They grab power from an engine or motor and turn it into fluid power. This fluid pushes parts like cylinders or motors to make the machine dig, lift, or move. If the pump’s not doing its job, your machine might act sluggish or stop completely.

The pump’s big task is to send fluid out at just the right pressure and speed. This helps your machine lift heavy loads, move smoothly, or react fast. For example, when an excavator scoops dirt, the pump makes sure it’s strong and steady. If your machine feels slow or wobbly, the pump might be the troublemaker.

Picking the wrong pump can mess things up. It could get too hot, make funny bubbles in the fluid, or wear out other parts. That’s why you need a pump that’s just the right size and strength to keep your machine happy and working well.

How Do You Know When It’s Time to Replace Your Pump?

Catching pump problems early saves your machine from big trouble. One clue is when your machine moves slower than usual. Maybe it takes forever to lift a bucket of dirt or feels weak when pushing heavy stuff.

Another sign is if it can’t keep pressure when lifting something heavy. This happens when the pump’s insides are worn out, letting fluid sneak past where it shouldn’t. That makes the machine less powerful, like a bike with a flat tire.

Listen up for odd noises, like grinding or banging, or if the machine shakes too much. These mean something’s wrong inside, like parts not lining up or air bubbles popping in the fluid. Those bubbles can scratch up the pump over time.

If your pump feels super hot, that’s bad news too. It might mean parts are rubbing too hard or the fluid’s dirty. When you spot these signs, it’s time to swap out the pump quick to avoid bigger headaches.

What Should You Evaluate Before Choosing a Replacement Pump?

Choosing a new pump takes some thinking. You gotta make sure the pump’s size and flow match your machine exactly. If they’re off even a little, your machine might move funny or break other parts.

Check if the pump can handle your machine’s top pressure. A weak pump won’t cut it for heavy jobs and will break fast. A too-strong pump might waste power if it’s not set up right, like using a sledgehammer to crack a walnut.

The pump’s shape and how it connects to your machine need to be perfect. If the bolts or shafts don’t line up, you’ll get broken parts or extra wear. Also, think about the fluid your machine uses. Some fluids need special seals, like ones called Viton or Teflon, to work right.

If you’re working in dusty spots, like a construction site, pick a pump that can deal with dirt. Hantang makes pumps with tough filters to keep the fluid clean and the machine running smoothly.

Is It Better To Choose OEM Specifications Or Aftermarket Replacements?

Deciding between OEM pumps and aftermarket ones is like choosing between a name-brand snack or a cheaper one. OEM pumps are made to fit your machine’s original design. They slide right in and work like the old pump, so you don’t have to change anything.

Aftermarket pumps might cost less, but they can be tricky. If their size or parts aren’t spot-on, they won’t fit right, and you might break something. Always make sure aftermarket pumps come from a company you trust, with good tests to back them up.

Hantang offers pumps that match OEM standards but are built extra tough. They’re a great pick to keep your machine running without any surprises, like a trusty pair of boots that never let you down.

Which Pumps Are Right For Your Specific Equipment Applications?

How Can You Ensure Proper Installation To Maximize Pump Life?

Putting in a new pump isn’t just about bolting it on. You gotta be extra careful:

• Clean all the pump’s holes and the fluid tank super well before you start.
• Swap out old filters to keep dirt out.
• Make sure the pump’s connection parts line up just right. Use tools to double-check if you need to.
• Fill the pump with fluid before turning it on to stop air bubbles from forming.
• Watch the pump closely when you start it to make sure it’s acting normal.

These steps keep your new pump safe and make it last way longer, like taking care of a new bike.

What Maintenance Practices Extend The Life Of Your New Pump?

Once your pump’s in, keep an eye on it to make it last:

• Learn what’s normal for your pump, like how hot it gets, how fast it pumps, or what sounds it makes.
• Check the seals, bearings, and filters often to catch problems early.
• Use cool tools like heat sensors or vibration checkers to spot trouble before it gets big.

FAQ

Q1. How do I know if my hydraulic main pump has internal leakage?
A: If your machine moves slow even when you push it hard, or if the pump gets really hot, it might be leaking fluid inside.

Q2. Can I install a higher-pressure-rated pump than my original one?
A: Yes, but only if your machine’s pipes and parts can take it. Too much pressure can break stuff.

Q3. How often should I replace my suction filters after installing a new pump?
A: Change them after 50 hours of use at first. Then check Hantang’s tips based on how much you use the machine or how dirty the filters look.
