Zeco Decanting Centrifuges

The design of these centrifuges reflects more than 75 years of research, developement, and field experience in centrifuging drilling mud. Built to process unweighted, as well as weighted mud. They are rugged user friendly machines designed for reliable operation year after year.

ZECO centrifuges have received many recent design upgrades which include:

-Heavier stainless steel scroll maintains balance better and longer.

-Conveyers use tungsten carbide tiles for superior wear.

-Enlarged conveyor descharge ports.

-Double flight conveyors greatly increases tonnage over single flight models.

-Thicker heavier stainless steel bowl for better balance.

-Adjustable fluid discharge ports on bowl.

-Enlarged solids discharge ports.

-Bowl has wall cake strips to prevent slipping (causing rotating plug).

-Extra solid wiper bars for longer life.

-Gearboxes use bronze bushings (no bearing) for longer life.

-Gearboxes feature internal oil pumps for superior lubrication.

-Designed for greater G-force 1727@2600 RPM.

-Timing belt drive reduces side load on bearings.

-Allen Bradley starters and controls (the best on the market).

Two Models are available:

The ZECO I (18" x 28" bowl)

The ZECO II (18" x 48" bowl)

1. Simple compact design

2. Effeciently remove fine solids

3. Unattended operation

4. Low operation cost

5. Low maintenance

6. High reliability

ZECO Mud/Gas Separators

Mud/Gas Shear Plates

Greatly Increase Efficiency

Unique to ZECO

ZECO Linear Motion Shale Shakers

Increased Flow Capacity

Longer Screen Life

Drier Discharge

Rugged and Simple

Low Maintenance

ZECO Mud Cleaners

The ZECO Mud Cleaner uses a unique two-stage mechanical process to remove fine drill solids. By a combination of cycloning and screening, the entire circulating volume is stropped of sand without significant loss of valuable wighting materials, chemicals, or fluids. The ZECO round Mud Cleaners can be doubled screened to efficiently return LCM to the active system.

- 400 GPM Capacity

Field application has these proven benifits:

- Chemical Treatment is reduced and mud costs are lower.

- Bit life and penetration rates are increased.

- Filter cake properties are improved and the danger of differential sticking is minimized.

- Cementing problems are reduced.

- Waste disposal problems are reduced.

ZECO Vacuum Degasser

ZECO degassers provide effective degassing with high throughput by means of a unique centrifugal-vacuum design. ZECO degassers are capable of handling high vescosity 20 pound mud with a 50% gas cut. They can draw up to 800 GPM and discharge as much as 400 GPM. The ZECO degassing system is totally self contaied on one skid. Both suction and discharge pumps are powered by a single electric motor.

HOW IT WORKS

The mud is drawn into the degasser by a vacuum pump at a constant vacuum level and spins in the centrifugal degassing tubes at forces up to 25 g's. Mud flowing through the degassing tube inlets desperses in thin layers around the tube walls to maximize exposure of the mud surface to vacuum. As the mud spins through the tubes, the lighter, entrained gas bubbles "rise" to the surface of the mud where they burst. The heavier mud is sprayed, with considerable impact, into a turbulence hood, breaking out remaining gasses. Gas is discharged through a blower to atmosphere or to a flare line. Degassed mud is returned to the mud system through a specially designed centrifugal deischarge pump.

Field proven performance. For 30 years the impact, plus turbulence principle of degassing has been proven successful. It employs a simple concept of degassing gas cut mud in a clean, safe and efficient manner.

The degasser consists of a submerged centrifugal pump and an elevated spray tank. Spiral ducting of the pump inlet causes the mud to form a whirlpool above the center of the impeller. Any gas that leaves the mud in the impeller moves to the whirlpool and escapes upward through the pump frame.

The gas cut mud in the impeller flows up through the riser pipe to the spray tank. A disc valve above the end of the riser pipe forms circular orifice which the mud flows through, forming a high velocity sheet. The mud sheet strikes the inside wall of the tank with enough turbulence and mixing to drive the small gas bubbles out of the mud.
