Daemo DMB Standard Series Seal Kits For Hydraulic Breaker Repair

Product Introduction

The Daemo DMB Standard Series Seal Kits For Hydraulic Breaker Repair are designed for hydraulic oil leakage repair, sealing system replacement, and regular maintenance of excavator-mounted rock breaking hammers. These seal kits are suitable for DAEMO DMB SERIES hydraulic breakers, including common Daemo DMB Standard Series models such as DMB50, DMB70, DMB90, DMB140, DMB180, DMB210, DMB220, DMB230, DMB250, DMB300, DMB360, and DMB450.

Hydraulic breaker seal kits are important repair parts inside the breaker hammer. During demolition, quarrying, mining, road construction, trenching, and concrete breaking, the hydraulic breaker works under high pressure, strong impact vibration, high oil temperature, and continuous operation. The seal kit helps prevent hydraulic oil leakage, maintain pressure stability, protect internal components, and support smooth breaker performance.

When the seal kit becomes worn, aged, hardened, cracked, or damaged, the hydraulic breaker may show oil leakage, weak impact, unstable frequency, abnormal heat, low working efficiency, or complete failure. Replacing the damaged seal kit in time can help restore hydraulic pressure, reduce oil loss, protect the piston and cylinder, and extend the service life of the hydraulic breaker.

This product is an aftermarket replacement seal kit compatible with DAEMO DMB SERIES hydraulic breakers. The DAEMO and DMB model names are used only for compatibility reference.

Materials

Our Daemo DMB Standard Series seal kits can be made with different sealing materials according to working position and customer requirements. Common materials include FKM, PU, NBR, PTFE, rubber, and backup ring materials.

FKM offers good oil resistance, heat resistance, and chemical stability. It is suitable for hydraulic breaker sealing positions that require long-term resistance to hydraulic oil and working temperature.

PU has excellent wear resistance, elasticity, and high-pressure sealing performance. It is commonly used in dynamic sealing positions where movement, pressure, and friction are frequent.

NBR is a widely used rubber sealing material with good oil resistance and cost efficiency. It is suitable for many general hydraulic sealing applications.

PTFE has low friction and good chemical resistance. It can be used in support rings, guide rings, or sealing positions requiring smooth movement and stable performance.

The correct combination of materials helps the seal kit perform reliably under high-pressure and high-impact hydraulic breaker working conditions.

Product Features

The Daemo DMB Standard Series hydraulic breaker seal kit is designed to help stop oil leakage and restore sealing performance. Each kit is matched according to breaker model and sealing structure. Accurate size is very important because even a small mismatch may cause installation difficulty, oil leakage, seal damage, or short service life.

The seal kit works together with the piston, cylinder, back head, front head, accumulator system, and hydraulic oil circuit. When the sealing system performs properly, the breaker can maintain better impact force and reduce internal pressure loss. This helps improve working efficiency during demolition, road repair, quarry secondary breaking, mining, trenching, and concrete removal.

A good seal kit should have oil resistance, wear resistance, pressure resistance, heat resistance, and stable elasticity. It should also be easy to install when the correct model is selected. For repair workshops and spare parts distributors, accurate seal kit matching is very important because it directly affects repair quality and customer satisfaction.

Main Advantages

The main function of the Daemo DMB Standard Series seal kit is to solve hydraulic oil leakage and help the breaker return to normal working condition. Compared with ignoring small leakage problems, replacing the seal kit in time can reduce the risk of more serious damage.

If the breaker continues working with damaged seals, hydraulic oil may leak out, pressure may drop, and internal components may wear faster. The piston, cylinder, bushings, and other parts may also be affected. Timely replacement of seal kits can help reduce downtime, control repair cost, and protect the hydraulic breaker assembly.

These seal kits are suitable for regular maintenance, urgent repair, hydraulic breaker rebuild, and spare parts stock. They are widely used by hydraulic breaker repair shops, machinery parts distributors, construction contractors, quarry operators, mining companies, and equipment rental fleets.

FAQ

Q1: Are these seal kits original DAEMO parts?
No. These are aftermarket replacement seal kits compatible with DAEMO DMB SERIES hydraulic breakers. The DAEMO and DMB model names are used only for compatibility reference.

Q2: What materials are used in the seal kits?
Common materials include FKM, PU, NBR, PTFE, rubber, and backup ring materials. The material combination depends on the sealing position and breaker model.

Q3: Can the seal kit stop hydraulic oil leakage?
Yes, if the leakage is caused by worn or damaged seals and the correct seal kit is installed properly. If the piston, cylinder, or sealing surface is damaged, those parts should also be inspected.

Q4: How do I confirm the correct seal kit model?
You can provide the breaker model, nameplate photo, old seal kit photo, seal dimensions, part number, drawing, or sample. We can help confirm before production or shipment.

Q5: When should I replace the seal kit?
The seal kit should be replaced when the breaker has oil leakage, weak impact, unstable operation, abnormal oil temperature, or during regular overhaul and rebuild.

Q6: Can I order seal kits with other hydraulic breaker spare parts?
Yes. Seal kits can be supplied together with chisels, pistons, bushings, diaphragms, rod pins, through bolts, cylinders, front heads, back heads, buffer plates, and wear plates.

Q7: Who usually buys this product?
This product is commonly purchased by hydraulic breaker repair workshops, spare parts distributors, construction companies, equipment rental companies, quarry operators, mining companies, and breaker service providers.
