IDECO 660-A Pump

Power end: for endless durability

Solid architectural philosophy

The power end frame of MM-600-A is welded with high-strength low-alloy steel and heat treated after welding.

Crankshaft and pinion shaft-the heart of power transmission

The crankshaft MM-600-A is made from a single piece of high grade alloy steel by forging process instead of the usual casting process.

Lubrication system-the lifeblood of the machine

MM-600-A adopts the dual lubrication system of the combination of forced lubrication and splash lubrication. Key bearings and motion pairs are pressure-lubricated by separate pumps to ensure adequate oil film protection during start-up and low-speed operation.

Bearings and crossheads

All shafts at the power end are supported by heavy-duty roller bearings to withstand heavy radial and axial loads. The crosshead guide plate is made of wear-resistant replaceable bronze material, which ensures the high precision and low wear of the crosshead in long-term reciprocating movement, and simplifies the later maintenance work. Every detail of the power end, from material selection to design, runs through the core concept of durability and easy maintenance.

Hydraulic end: control high pressure environment

The inevitability of forging

Each module is machined from a solid forging stock of high-quality alloy steel, such as 35CRMO or 40CRMNMO.

Cylinder linerーー the first line of defense against wear

Option 1: Industry benchmarkーー high chromium bimetal cylinder liner

Structure and material: this kind of cylinder liner adopts double-layer composite structure. The casing is made of high-strength 45 # forged steel with a tensile strength of over 610 MPa, providing strong compression support to the liner. The inner bushing is made of high chromium cast iron by centrifugal casting process, in which the chromium content is more than 27% , and alloying elements such as molybdenum are added to increase the hardness depth.

Process and precision: centrifugal casting ensures the uniform distribution of chromium carbide in the high chromium cast iron lining. After precise heat treatment, the hardness of the inner hole can reach Rockwell hardness HRC 62-69, with strong wear resistance. The cylinder liner adopts"HP" lip design, which effectively prevents the sliding of the inner liner under high pressure.

Performance expectations: high chromium bimetallic liners are designed to last more than 800 hours under conventional drilling conditions, providing customers with a reliable and economical solution.

Option 2: The Ultimate Solution-zirconia ceramic liners

Advanced Materials Science: Zirconia (ZRO2) is a high-tech ceramic material, its comprehensive performance far beyond the traditional high-chromium cast iron and alumina ceramics. Compared with alumina ceramics, zirconia has significantly higher fracture toughness and impact strength, which greatly reduces the risk of cylinder liner fragmentation caused by accidental impact in the field.

Extreme Process: the inner hole of zirconia inner liner is honed with precision, and the surface finish can reach 4-8 RMS, which is 3-4 times finer than that of alumina ceramic. This mirror-like smooth surface greatly reduces the coefficient of friction with the piston. It also has a high degree of hardness
Rockwell hardness HRC 92-94, unparalleled wear resistance.

Performance and total cost of ownership (TCO) : the service life of zirconia ceramic cylinder liners can reach an amazing 4000 hours or more, which is several times that of high chromium cylinder liners. The value goes far beyond that:

Extending the life of a piston: a very low coefficient of friction can extend the life of a piston by up to five times.

Reduced downtime: longer maintenance cycles mean fewer downtime changes, directly reducing labor costs and increasing valuable drilling time.

Piston-the peak of sealing technology

Bonded polyurethane pistons: preferred for oil-based mud and high pressure (up to 7500 psi) applications. The"Nose" design, made of two different hardness of polyurethane material and steel core firmly bonded together, can effectively resist wear, high temperature (up to 220 °F/104 °C) and extrusion deformation.

Bonded Rubber Pistons: a reliable choice for durability and economy in water-based mud. The piston body is made of tough Bunan rubber and bonded with the core and hub. It has high structural strength and can work at a maximum temperature of 250 °F (121 °C) .

High temperature and high pressure (HTHP) pistons: for extreme drilling environments, we also offer specialty polyurethane pistons designed to operate up to 325 ° F (163 ° C) , ensuring seal integrity under the most demanding conditions.

Valves, seats and piston rods-invisible strength props

Valve Assembly: the body and seat are forged from high quality alloy steel and heat treated with carburizing. Provide full open, three reinforcement, four reinforcement and other designs to adapt to different fluid characteristics and cuttings requirements, and with high-quality polyurethane valve glue, prolong service life and easy to replace.

Piston rod and intermediate push rod: these parts are made of high quality heat-treated alloy steel, the working surface is induction hardened and precision polished to achieve mirror effect.
