Product Details

The polyurethane mud pump piston head is a high-performance core component developed by our company based on our mature polyurethane elastomer technology. It is widely used in mud pump equipment for applications such as mining, oilfield operations, geological exploration, and river dredging. As a critical sealing and transmission element operating under conditions of high pressure, severe abrasive wear, and highly corrosive media, its performance directly determines the continuous operational lifespan and construction efficiency of the mud pump.

The core function of this product is to achieve dynamic sealing and power transmission between the piston and cylinder liner during the reciprocating motion of the mud pump, effectively withstanding the impact of high-pressure mud and resisting the intense erosion caused by abrasive particles in the medium. Its exceptional performance stems from a specialized polyurethane formulation and precision manufacturing processes, providing unparalleled wear resistance, outstanding tear resistance, and excellent media compatibility. This significantly extends equipment service life, reduces downtime, and creates greater value for customers.

Performance characteristics

Excellent wear resistance: This product features a special polyurethane formulation that delivers wear resistance 3 to 5 times greater than that of conventional rubber. The product’s hardness is precisely controlled at 90±5 on the Shore A scale, striking an optimal balance between high wear resistance and excellent elasticity.

Excellent voltage resistance performance: The product’s maximum working pressure can reach 40 MPa. Its unique structural design effectively ensures sealing stability under high-pressure conditions, guaranteeing long-term stable operation even in extreme service environments.

Excellent temperature resistance: This product can be used reliably and stably for extended periods in high-temperature environments up to 120℃. Its operating temperature range spans from -30℃ to +120℃, and it boasts excellent antioxidant and heat-aging resistance, ensuring outstanding durability and reliability even under wide temperature ranges and at high temperatures.

Wide media resistance: Outstanding media compatibility—demonstrating excellent resistance to both water-based and oil-based muds. It exhibits exceptional acid-alkali resistance and remains stable over a wide pH range of 3 to 13.

Strong mechanical performance: While possessing high tensile strength and excellent tear resistance, it also exhibits outstanding elasticity and cushioning performance, effectively absorbing impacts and protecting equipment.

Innovative self-lubricating properties: Good self-lubricity can achieve a lower coefficient of friction, effectively reduce operating resistance, and help extend the service life of the piston head itself as well as its mating components.

Use

Industrial equipment, machine tools, petrochemicals, agricultural machinery, wind power industry, coal mining machinery, farm machinery, and industrial automation fields.

Transportation and storage

① Avoid extreme temperatures: During transportation, the product should be kept away from prolonged exposure to environments above 40℃ or below -20℃. Although the product itself has a wide temperature tolerance range, extreme temperatures may affect its initial physical state.

② Ideal storage conditions: The product should be stored in a cool, dry, and well-ventilated warehouse. It is recommended to maintain the ambient temperature between -20℃ and +30℃, with relative humidity preferably below 70%.

③ Avoid ozone and light exposure: The storage location should be kept away from equipment that generates ozone (such as high-voltage electrical appliances and motors), and direct sunlight or strong artificial ultraviolet light sources should be avoided in any form, to prevent surface aging and cracking of the material.

④ Keep in original packaging: Before putting the product into use, please try to keep it in its original factory-sealed packaging to prevent contamination by dust and impurities.

⑤ Follow the “First-In, First-Out” principle: When managing inventory, the “First-In, First-Out” principle should be followed to ensure that products with the longest storage times are used first.

Recommended Products

Turning cylindrical workpieces (polyurethane cast pipes)

Polyurethane billets, grade 95ES, are polyurethane turned billets designed for general-purpose sealing applications. They can operate continuously over a temperature range from -40°C to +90°C and feature three key characteristics: ease of machining, low compression set, and high resilience—offering excellent value for money.

Vulcanized rubber (polyurethane valve seal)

Valve rubber, also known as “valve diaphragm,” is an elastic sealing element made from highly abrasion-resistant polyurethane (PU). It is installed between the valve body and valve seat of fracturing pumps, mud pumps, and cementing trucks, serving as a unidirectional valve seal. Its service life directly determines the number of consecutive fracturing stages and the efficiency of the operation.

Cold-weather protective gear for ice and snow sports

The polyurethane cold-weather protective gear for ice and snow sports is specially designed for extremely cold environments, directly tackling the extreme temperature challenges ranging from -20°C to -45°C and maintaining outstanding performance even in severe cold.
