National Oilwell Varco (NOV) is an American multinational corporation based in Houston, Texas. It is a leading worldwide provider of equipment and components used in oil and gas drilling and production operations, oilfield services, and supply chain integration services to the upstream oil and gas industry. The company conducts operations in more than 600 locations across six continents, operating through three reporting segments: Rig Technologies, Wellbore Technologies, and Completion & Production Solutions. National Oilwell’s two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks.

GDEP is the original creator of the drilling pump and continues to set the standard for durable, high-quality drilling pumps that can withstand the world’s toughest drilling environments. Starting with our PZ7 and rounding out with the market"s most popular pump, the PZ1600, our PZ Series of pumps are the perfect choice for today"s high-pressure drilling applications.

We carry mud pumps, connecting rods, and more than 2,000 drawings and blueprints of oilfield equipment and supplies. We can fill your orders with one-of-a-kind designs for:

Our vast inventory of fluid-end and gear-end parts for duplex pumps includes more than 500 duplex liners, as well as cages and stuffing boxes. If you can’t find the model you are looking for below, let us find it for you.

We carry more than 1,500 duplex piston rods and 200 duplex pony rods in our inventory. Though we keep in stock connecting rods primarily for GA550 and GA750 models, other options are available, including custom connecting rods for most duplex and triplex mud pumps.

We now offer crossheads and guides for both EMSCO D-375 and DB-550 duplex pumps. We also have slides and shoes for certain models. If you don’t see a part you need, let us find it for you.

A mud pump is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi (52,000 kPa)) down the drill string and back up the annulus. A duplex mud pump is an important part of the equipment used for oil well drilling.

Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplex’s with five horizontal piston/plungers. The advantages that Duplex mud pumps have over convention triplex pumps is a lower mud noise which assists with better Measurement while drilling and Logging while drilling decoding.

Use duplex mud pumps to make sure that the circulation of the mud being drilled or the supply of liquid reaches the bottom of the well from the mud cleaning system. Despite being older technology than the triplex mud pump, the duplex mud pumps can use either electricity or diesel, and maintenance is easy due to their binocular floating seals and safety valves.

A mud pump is composed of many parts including mud pump liner, mud pump piston, modules, hydraulic seat pullers, and other parts. Parts of a mud pump:housing itself

Duplex pumps are used to provide a secondary means of fuel transfer in the event of a failure of the primary pump. Each pump in a duplex set is sized to meet the full flow requirements of the system. Pump controllers can be set for any of the following common operating modes:Lead / Lag (Primary / Secondary): The lead (primary) pump is selected by the user and the lag (secondary pump operates when a failure of the primary pump is detected.

Alternating: Operates per Lead / Lag (Primary / Secondary) except that the operating pump and lead / lag status alternate on consecutive starts. A variation is to alternate the pumps based on the operating time (hour meter) of the lead pump.

The 2,200-hp mud pump for offshore applications is a single-acting reciprocating triplex mud pump designed for high fluid flow rates, even at low operating speeds, and with a long stroke design. These features reduce the number of load reversals in critical components and increase the life of fluid end parts.

The pump’s critical components are strategically placed to make maintenance and inspection far easier and safer. The two-piece, quick-release piston rod lets you remove the piston without disturbing the liner, minimizing downtime when you’re replacing fluid parts.

Before any maintenance work is carried out, read the pump safety guidelines thoroughly and ¡ apply whenever applicable. Periodically review the information in the safety section with all persons who operate or work ¡ on the pumps.

WARNING! Wear safety harnesses, and ensure safe access is provided to all mud pump items which ¡ cannot be reached from floor/deck level.

Work on the mud pump may only be performed by physically, mentally and technically ¡ competent, duly authorised and certified personnel. Use the permit to work system (PTWS)! ¡ The work area must be adequately lit to assure sufficient all round vision. ¡ Hydraulic hand pump pressure gauges must be calibrated periodically. ¡ Maintain a good housekeeping regime during any service/repair on the mud pumps. ¡ Spare parts should always meet the technical requirements specified by the manufacturer. ¡ This is ensured when using MHWirth original spare parts. Ensure that adequate and suitable tools and equipment are available to perform all mainte- ¡ nance work. Mud pump consumables

CAUTION! Pump, motors, lubrication oil, pipe work and gearboxes may reach temperatures approach- ¡ ing 60°C during normal operation. Maintenance personnel shall be made aware of this and sufficient cooling off time shall be allowed before commencing work on hot parts.

WARNING! Stop and isolate the mud pump from all sources of hydraulic energy and the electrical power ¡ supply as per the operator’s lock out procedure. The pump must be completely depressurised before attempting any work on the fluid end or ¡ piston and liner assemblies. Bursting bladder of pre-charged suction and discharge dampener may cause serious injury ¡ to personnel and damage to equipment. Jets and leaks from high pressure oil may be fatal. Ensure the system is switched off, ¡ depressurised and locked out before any work is performed on the mud pump.

Use only adaptors and reduction pieces which have been approved by RK Kutting. ¡ The lines must be inspected at regular intervals. ¡ Before each installation, the hoses must be inspected for damage, kinks, wear, corrosion, ¡ cracks and other kinds of damage. It is absolutely essential to replace damaged hoses immediately. ¡ Use only hoses with a known working pressure. ¡ To extend the service life of the hose, use only clean media. ¡ If a malfunction is suspected, immediately shut down the product or machine in which the- ¡ hose is installed andreplace the hose. The maximum permitted operating pressure is determined by the weakest element in the ¡ installation.Mud pump consumables
