Shear pump is usually used together with Jet mud mixing unit, to be assembled as a jet shearing unit in oilfield solids control system.

Jet shearing unit

The jet shearing unit is formed by shear pump, mixing hopper, pipeline and polymer/clay hydrator. For installation transportation, the polymer/clay hydrator is formed by a separate compartment.

The pump should be located the liquid source so that the suction line can be short and reduce loses. The foundation should be sufficiently rigid and substantial to absorb any vibration and support the base plate at all points. The base plate should be installed in a level position.

Oilfield shear pump

The JQB series shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a electric motor. Included is a special hopper(ZHP150) with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved shaft seal.

There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your shear pump.

This document will deal with both general and specific recommendations for improved JQB series turbine shear performance in both oilfield and industrial applications.

World’s top 5 trenchless drilling rig manufacturers list collected by GN solids control.

As a trenchless drilling mud system manufacturer, GN has designed and manufactured many sets of complete mud cleaning/recycling system for trenchless drilling rigs, mainly used for horizontal directional drilling. Here we collect World’s top 5 trenchless drilling rig manufacturers list.

1 Vermeer (http://www2.vermeer.com/vermeer/AP/en/N/ )

2 Ditch Witch (http://www.ditchwitch.com/trenchless/directional-drills/ )

3 American Auger(http://www.americanaugers.com/ )

4 Astec Underground(http://www.astecunderground.com/)

5 Herrenknecht (http://www.herrenknecht.com/)

Vermeer and Ditch Witch are well known brand in the world.

1 Vermeer rig

There’s a lot to consider when purchasing or leasing a horizontal directional drill — features, durability, support, training and overall value. But one area often overlooked is the potential resale value of the unit.
Too often contractors will overlook the potential value of the machine after its useful life in their operation is over. In addition, as more contractors utilize leasing as an acquisition strategy, resale value becomes a more important component in the purchase decision.

Vermeer has distributor everywhere in the world, you can get good after-sales service from them easily.

To see GN solids control equipments for Vermeer trenchless rigs here:

Shale shaker, desander, desilter, decanter centrifuge, mud tank

GN solids control choose Italy Oli brand vibrating motor for all our shale shakers. Vibration motor is important components for shale shaker, I will introduce briefly about vibrating motor installation & maintenance.

1 How to install vibrating motor ?

 (1). Before installing vibrator, turn off and lock out/tag out all energy sources to mounting structure according to ANSI standards。

(2). If using a cutting torch or welding, test atmosphere for gas level or dust content.

(3). Make sure mounting surface is strong and flat, 0.25 mm acros vibrator feet. (This will minimize internal stress to vibrator casting when tightening mount bolts.

(4) Make sure mounting surface and vibrator are clean and free of debris, paint, and oxidation.

(5) Before installing vibrator onto mount, apply thread sealing compound to all bolts.

(6) After the vibrator has been operated for 10 to 20 minutes, check bolt torque. Tighten if necessary

2 How to  maintain  vibrating motor?

(1)Clean dust on shell regularly

(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker

(3) Inspect the cable, whether there is wear, hold down, crushing, etc.

(4) the vibration motor should be under good lubrication during operation:

Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃

During running, every 2000 working hours user should makeup LGHP2 lubricate grease once. Every bearing can not be filled over 25.8g.
