Title: New Moyno® Max-Flow Annihilator™ Grinder System Lowers Initial and Lifetime Costs, Saves Energy and Improves System Performance
Date Posted: Tuesday, 25 January 2011 00:00

The new Moyno® Max-Flow Annihilator™ Grinder System is a custom engineered headworks debris handling system that protects downstream pumps, valves and process equipment in water treatment plants and its lift stations. The cost-effective, low maintenance Moyno Max-Flow Annihilator replaces bar rakes and screens as well as drum screen grinders for enhanced performance.

The Max-Flow system contains two or more Annihilator grinders mounted side-by-side in a stainless steel retrieval frame in the headworks of a waste treatment system. They can be installed in an in-line or a staggered or offset design to accommodate a variety of channel widths.

The frame is engineered-to-order and pre-fabricated. It includes guide rails to permit the independent retrieval of each grinder for easy maintenance. Steel panels can also be inserted in place of a grinder to divert the flow to the remaining grinders during maintenance, eliminating the need for a diversion or by-pass channel. Stainless steel or FRP control panels can be installed to control the operation of each grinder independently using manual or automated control systems.

Additional Moyno Max-Flow Annihilator Grinder System benefits include the following:

• Fewer maintenance issues than bar rakes and bar screens and drum screens

• Lower maintenance costs

• Lower initial costs than competing technologies

• Lower energy usage since all grinders in the system don't need to operate continuously

• Better performance in reducing the particle size of debris floating through the waste treatment system

• Better environmental choice with processing of debris done under ground in the lift station

Title: New Moyno® 2000 Close-Coupled WA and WB Model Pumps Now Available
Date Posted: Thursday, 14 April 2011 00:00

The new Moyno® 2000 Model WA and WB Pumps provide unmatched performance in a compact, close-coupled configuration. Moyno 2000 WA and WB close-coupled pumps are specifically designed for lower pressure, lower flow applications that do not require the full features and benefits of the Moyno 2000 G1 pump. The Moyno 2000 WA and WB models are ideal for municipal and industrial applications that require the transfer of highly viscous fluids and solids where a close coupled configuration is preferred, but the robustness of a gear joint is desired.

The Moyno 2000 WA Pump features:

  • Bearings integral to the adapter housing that support the radial thrust loads at the rotor/stator
  • Standard size / keyed gear reducer shaft
  • Sealed, gear-type universal joint drive train
  • Optimized rotor/stator pumping element geometry

The Moyno 2000 WB Pump features:

  • Traditional close-coupled design with thrust and radial loads supported by the bearings in the gear reducer
  • No shaft bearings
  • Gear reducer output shaft designed with cross drilled pin holes for extended service life
  • Sealed, gear-type universal joint drive train
  • Optimized rotor/stator pumping element geometry
