Power End: the cornerstone of indestructible strength and stability

Power side frame construction: the cornerstone of performance

Wheatley fig. The power end of the 1024 is built from a sturdy, monolithic, fine-grained cast iron frame. Through precision boring process, we ensure the dimensional stability and perfect alignment of all internal components.

Crankshaft design: power conversion with precision and durability

Fig. The 1024 features Whitley's unique offset crankshaft design, forged or cast from high quality ductile iron or alloy steel. By offsetting the crankshaft, the design successfully reduces the vertical thrust load by more than 40% .

Gears and bearings: quiet and efficient power transmission

This pump uses the continuous tooth herringbone gear as the main gear, is made by the heat treatment spheroidal graphite cast iron, and by the forging alloy steel cutting pinion gear meshing 5. The crankshaft is supported by heavy-duty tapered roller bearings.

Lubrication system: the lifeblood of the power end

The power end is lubricated by a splash lubrication system with crankcase oil grooves 7. Bearings are sealed in a separate pressure oil gun lubrication housing.

Hydraulic end: designed for abrasive conditions and easy maintenance

Hydraulic end module: pressure bearing core

Wheatley fig. 1024 uses a monolithic hydraulic end made of high-quality ductile iron.

Cylinder liner and piston: main wear interface

The pump features hardened steel liners and a Mission-style mud pump piston with replaceable rubber lining. Available in a wide range of liner/piston sizes from 2"To 4".

Cylinder liners: hardened steel cylinder liners provide a durable surface that resists wear and tear from drilling mud. The material is heat-treated to achieve a high surface hardness while retaining a ductile core that resists cracking under pressure cycles.

Pistons: a piston with replaceable rubber is a key design for maintainability. Instead of replacing the entire piston assembly, field personnel can quickly and cheaply replace the worn rubber seal, significantly reducing maintenance costs and downtime. The piston body is made of durable cast iron or steel to withstand high-strength reciprocating loads.

Valve and seat: The Guardian of flow

Steel winged pilot valves and seats are standard on the hydraulic end for mud and mud conditions. Valve rubber is usually made of durable nitrile rubber or polyurethane for reliable sealing with metal seats. The choice of valve skin material allows the user to optimize under different operating conditions-nbr for normal and water-based slurries, and polyurethane for oil-based slurries or higher wear applications.

Piston rod and packing: dynamic sealing system

The piston rod is made of case hardened steel. The stuffing box consists of a lip-shaped packing ring and a lubricated packing gland. The piston rod surface is hardened and finely polished to minimize friction and wear with the packing. The lubricating packing gland system forms a reliable seal that prevents high-pressure mud from leaking from the hydraulic end and prevents contaminants from entering the power end
