Exceptional Power-to-Weight Ratio
While delivering powerful performance up to 847 HP, the Eweco mud pump maintains a net pump weight of 22,500 lbs. This outstanding design sets a new benchmark in the industry, saving customers significant costs and time in equipment transportation, lifting, and site layout. It is particularly suitable for offshore platforms with limited space or land rigs requiring rapid mobility.
Lower Total Cost of Ownership (TCO)
The core of EWECO's design philosophy is to create long-term value for customers. Through the use of more durable forged steel crankshafts, longer-life full roller bearings, a reliable dual lubrication system, and high-quality fluid end wear parts, the Eweco mud pump's Mean Time Between Failures (MTBF) is significantly improved.
Comprehensive Compatibility and Support
As an OEM manufacturer, we are committed to providing full support for every EWECO pump. We maintain a complete inventory of mud pump spare and wear parts, ensuring you have access to components that perfectly match the original equipment when needed, thus guaranteeing the pump's optimal performance and reliability.
Oil and Gas
Both onshore and offshore oil/gas rigs rely heavily on mud pumps to drill the deep wells required to extract petroleum resources from reservoirs.
Water Wells
Mud pumps are key to efficiently drilling water wells for municipal, agricultural, and industrial uses.
Mining
Mineral exploration, production drilling, and other mining activities universally use mud pumps for their drilling needs.
Geothermal
Getting geothermal energy from the Earth requires drilling into very hot rock formations deep underground - mud pumps make this possible.
Tunneling
The huge tunnel digging machines generally need mud pumps to constantly circulate the drilling fluids and help with the digging.
Potash Mining
Mud pumps are essential for drilling the injection wells used in solution mining of potash deposits.
Construction
For drilling foundation piles, caissons, and other construction applications, mud pumps are often employed.
- Whether the pressure of the oil lubrication pump is within (20-30Psi).
- Listen to determine whether there is any horizontal or vertical abnormal sound at the liquid end.
- Observe whether the clamp bolts are loose and whether the tail of the piston is leaking mud when operating.
- Observe whether mud is leaking from the three warning display holes of the cylinder liner flange seat, cylinder liner gland seat, and upper valve gland of the hydraulic cylinder.
- Observe whether the cylinder liner is shaking, loosening or moving.
- Observe whether the pump pressure is stable and whether the water hose swings.
- Test the driving shaft bearing, crankshaft bearing and frame for local overheating (temperature rise <70°C)
- Listen to determine whether there is any impact noise at the power end
- Observe whether the spray pump is leaking or the water spray volume is reduced.
- Observe whether the mud purification is effective and whether there are any grinding substances in the mud.
- Check whether the opening and closing positions of the ground manifold gate group are correct to prevent short mud circulation.
- Observe whether the seals are leaking and whether the fasteners are loose at any time.
- Use the special tools provided with the pump correctly and do not operate in violation of regulations.
