GARDNER DENVER PZ10 Pump

Core technical specifications

Gardner Denver PZ-10(PZK) performance data sheet (by cylinder liner size)

Superiority of ductile iron frame

PZ-10 power end of the frame, eccentric shaft and connecting rod and other core structural components, using high-strength Nodular Iron (Nodular Iron) whole cast.

Precision Drive and bearing system

The PZ-10's power train is designed for smooth, efficient torque transmission.

Drive Gear: the main gear is forged from high-quality alloy steel, subjected to rigorous heat treatment and designed with Double Helical teeth.

Bearing Configuration: The Power End adopts full roller bearing structure to cope with the severe load conditions. The eccentric shaft (crankshaft) is supported by double-row spherical roller bearings, which can withstand extremely high radial loads and certain axial loads at the same time, and have a self-aligning function to compensate for potential installation errors and frame deformation. Double out of the pinion shaft (Jack Shaft) by heavy-duty straight roller bearing load, to ensure the high speed rigidity and stability.

Crosshead and connecting rod: the big end of the connecting rod adopts double row roller bearings, and the small end is connected with the crosshead pin to ensure the accuracy of the movement. The crosshead slide plate is made of replaceable bronze. This self-lubricating material effectively reduces friction, prolongs the service life of the crosshead and the rack guide, and is easy to replace on site, greatly simplifying maintenance.

Wrought alloy steel cylinder module

The Fluid End of the PZ-10 has an interchangeable modular design, and the core component, the Fluid End Module, is forged from a single piece of high-quality alloy steel (35CrMo, 40CrMnMo, or 4135) .

API-7 standard valve assembly

Valve Design: PZ-10 standard with Api-7 # standard three-ribbed valve assembly. We also offer Full Open valves as an option. The fully open valve has a larger flow area, which can effectively reduce the resistance and turbulence of the fluid, and reduce the erosion of the valve body and valve seat. It is especially suitable for high displacement and high solid content drilling fluid.

Material Selection: to adapt to the chemical and physical characteristics of different drilling fluids, valve plug-in provides a variety of material options. Standard configuration for high-performance Polyurethane plug-ins with excellent wear resistance and elasticity. For high temperature or special chemical environment, but also choose Nitrile Rubber (Nitrile Rubber) and other special materials.

Convenient Maintenance: the valve cover of the hydraulic cylinder adopts threaded design. Compared with the traditional bolted flange connection, disassembly and assembly are faster, which can significantly shorten the shutdown time for on-site replacement of valves and seats and improve operation efficiency.

Cylinder liner selection and material specification

The cylinder liner is the core wearable part which bears the reciprocating motion of the piston and the flushing of the drilling fluid directly in the hydraulic end. We offer two mainstream cylinder liners to meet different durability and cost requirements.

List of pistons, piston rods and related components

The piston assembly and the piston rod are the key components to transmit the linear motion of the power end to the drilling fluid.

List of spare parts for power end and hydraulic end

To facilitate customer maintenance planning and spare parts procurement, the following table lists some of the key wearing parts of the PZ-10(PZK) and their original part numbers. Be sure to provide the pump type (PZK) and serial number when ordering.
