This Moyno progressing cavity pump promises performance enhancing features in upper and lower-deck applications on floating production, storage, and offloading vessels.

The company says its pump is capable of cost effectively handling clean and oily liquids as well as corrosive fluids and thick, abrasive slurries and sludges, even with viscosities of more than 1 million cps.

The product line includes models capable of generating flow rates as high as 2,500 gpm and pressures to 2,100 psi.

Pumps offer low maintenance, dependability, and long service life, which yield low overall total cost of ownership in top-side and hull-side applications, the firm says. The pump's high performance, progressing cavity design results in a gentle, low shear, pulsationless discharge.

A variety of proprietary Ultra-Flex stator elastomers and Ultra-Shield rotor coatings helps sustain peak pumping efficiencies, minimize maintenance, and extend useful service life even in the most corrosive, abrasive service environments.

Typical applications include:

  • Desalter.
  • Low pressure and high pressure flare.
  • Closed drain.
  • Sludge drain
  • Oily bilge water.
  • Diesel fuel generator feed.
  • Drilling mud transfer.

New globe control valve

The new Mark 100 globe control valve is designed for improved capacity, extra-fine control, and easy maintenance.

The firm says its valve delivers higher capacity in a smaller valve than conventional globe control valves in sizes 6-16 in. and pressure classes 150-600.

Its wide, streamlined gallery helps increase capacity. This provides end users cost savings by often allowing a drop in valve size.

For instance, a 10 in. Mark 100 has a tested capacity comparable with the catalog capacity of competitors' 12 in. valves, the company says.

Available with a full range of noise and cavitation reduction severe service trims, the valve can be used for chemical manufacturing, oil and gas production, and power generation.

The Mark 100 also utilizes long strokes that enable it to provide precise flow—even under rigorous demands—reducing waste and increasing the purity of a final product in applications such as chemical processing.

With top-entry clamped seats, heavy stems, and an integral body stand, this globe control valve allows easy maintenance and helps reduce downtime.

New technology aids drillbit operations

Newly released Z3 polycrystalline diamond compact (PDC) cutter technology for fixed cutter drillbits promises a step-change advance in the abrasion resistance of PDC cutters, leading to significantly longer and more cost effective drilling operations.

The company says this technology will help as it expands the application of its FM 3000 PDC product line into hard rock and more abrasive formations.

Combining these two technologies with DatCi (design at the customer interface) process will provide greater performance and lower cost-per-foot drilled for customers, the firm says.

New Series C-9000 metering pumps are built for reliable delivery of corrosive, nonlubricating, and other thin fluids, including solvents, polyoils, and oils.

Designed with external spur gears, units promise superior metering, pulseless, repeatable flow, and precise dispensing of fluids with every shaft rotation under varying process conditions, the company says.

The new pumps are built with 316 stainless steel and compatible materials. Their housing features a precision ground and lapped three-plate assembly. Units are prepackaged with an integrated closed loop speed control and compact AC or DC motor drive assembly. With its hardened material construction and only three moving parts, pumps provide resistance to wear and corrosion.

Pumps are designed to thrive across a broader range of temperatures than earlier ones. The models operate at speeds as high as 1,000 rpm and deliver flows as much as 9,000 cc/min (2.4 gpm). They're equipped with metric thread or SAE 61 standard port connections with a magnetic coupling seat, a mechanical seal, or lip seal.
