mud pump packing for sale

Pump packing, for liquid ends of direct acting and power pumps, is used to provide a seal around a rod, plunger, or piston. For a piston, the packing is contained in a groove in the piston, and moves with the piston. For a rod or plunger, the packing is stationary and is contained by a stuffing box.

Is the most common plunger pump packing. It is comprised of nitrile butadiene rubber (NBR) with synthetic fabric around rigid phenolic core, medium hard, black. 838 packing is rated from -10 to +180°F, and up to 2,500psi. It is resistant to light and heavy hydrocarbons (liquids and gasses), propane, butane, gasoline, fresh water, saltwater, mild acids, mild chemicals, and most hydraulic fluids.

Is a plunger pump packing that is harder and tolerates higher temperatures, pressures, and abrasive fluids, than the traditional J-style 838 packing. It is made with high temperature resistant hydrogenated nitrile butadiene rubber (HNBR) with high strength synthetic fabric around a rigid phenolic core. 858 Gold packing is rated from -10 to +300°F, and up to 5,000psi. It is resistant to hydrocarbons, acids, H2S below 6%, abrasive fluids, fresh water, saltwater, propane, butane, gasoline, light or heavy oils, mild chemicals and acids, and most hydraulic fluids.

PPP also offers optional packing styles and materials for sale, such as Teflon, Kevlar, spring loaded packing, compression packing, die-formed packing sets, lip type packing, adjustable and non-adjustable, (V-Ring aka Chevron), PTFE (plastic), and others for the following types of low pressure high volume and high pressure low volume pumping services: produced water both saltwater and fresh water, NGL, gasoline, general service, acids, caustics, amine, glycol, RO, dirty liquid service, bentonite (mud), alkalis, and hydroxides.

During the 1950’s the Mission” 1780 type “W” pumps were introduced to replace duplex pumps while creating the first low pressure mud system. The use of a high quality concentric type centrifugal pump allowed abrasive fluids to be mixed and transferred while reducing initial and maintenance costs for the drilling industry. The low-pressure mud system with Mission 1 780 Type “W” centrifugal pumps became the industry standard.

As well depths increased so did the need for heavier mud weights. When the mud weight began exceeding 14 ppg the need for a pump that could withstand greater horsepower loads arose. During the 1970’s Mission organized a design team that engineered the Mission Magnum. The Magnum was designed to have the same footprint, flange locations, and drive shaft diameter as the 1780 “W”. This allowed a 1780 to be replaced by a Magnum without any skid modifications. The Magnums were originally engineered with a 2-1/2″ shaft (3″ between the bearings), double row bearings with an engineered life of over 2 years at 200 HP, larger impellers and heavier frames. The Magnum allowed drilling contractors to upgrade their centrifugal pumps and mix heavier fluids.

The National Oilwell Varco” Mission centrifugal pump line has proven to be the best centrifugal design for handling abrasive mud. This pump line offers a broad selection of innovative features for a variety of routine, demanding, abrasive and corrosive applications. These pumps are designed for a wide range of flow rates, from a few gallons per minute to thousands of gallons per minute.

Each pump contains the finest materials, engineering and craftsmanship available in the industry. Described are like features of these pump lines and unique features are described on the following pages.

National Oilwell Varco utilizes unique design features developed for slurries. Three major differences from most pump designs include the concentric casing, wider impellers and increased re-circulation areas. Each feature contributes to reducing wear when handling abrasive fluids.

All of the pumps feature a concentric casing. This casing averages 37% thicker than conventional pump casings, and up to 50% thicker for the larger, mud pumping models. They are pressure rated at 1 .5 times the flange rating and are designed with a 1 /8″ erosion allowance. The concentric style casing has proven to offer the greatest pump life and reduced downtime. The walls of a concentric style casing are an equal distance from the impeller throughout the impeller circumference, which results in a smooth flow pattern. A volute style casing has a cutwater point that disturbs the fluid flow pattern creating an eddy. The concentric casing eliminates vibration, turbulence and aeration that is caused by the cutwater point in conventional volute pumps. It also reduces the high bearing loads and shaft deflection even at near shutoff flows.

The shaft is much larger in diameter than conventional pump shafts for heavy-duty performance, minimum deflection and increased operating life of the seal or packing. With a 2-1/2″ diameter at the seal area and 3″ diameter between the bearings these pumps can be direct connected or belt driven.

The shaft area under the packing is protected by a replaceable, hook type sleeve with one end free to expand with temperature variation. This sleeve can be replaced in the field without shaft removal.
