City of San Antonio

Situation The City of San Antonio Public Services was experiencing excess vibration in their conveyor drive system.  This caused accelerated wear and tear on the equipment.  The City was also concerned about hydraulic fluid spilling from the existing fluid coupling The Solution Install a MagnaDrive MGTL-18/300 Magnetic Coupling. This coupling would replace the existing fluid

Grand Hyatt Hotel

Situation The Grand Hyatt experienced a number of complaints that water pressure on the upper floors (during periods of high occupancy) was insufficient. The Solution The Grand Hyatt decided to install MagnaDrive’s 10.5 ASDs in order to regulate water pressure and flow so that it could be tailored to occupancy levels and guest demand The

Chevron Corporation

Situation Because the oil tanker’s structure flexes while at sea, misalignment between the pump and its motor caused accelerated wear on the bearings and mechanical seals. This also caused vibration-related problems on the pump end. The Solution MagnaDrive installed a VTX-07 coupling on the oil transfer pump while the Vega Voyager was in port for

Fort Wainwright

Situation Severe misalignment of rigid couplings caused the Army to replace these couplings up to 4 times per year on each of their pumps. The Solution The Army decided to install MagnaDrive VTX couplings to not only solve their vibration issues, but also hoped to save energy by allowing the VTX couplings to slip. The Results The

Diavik Mines

Situation MagnaDrive distributor ANM Equipment was contracted to design a mine dewatering system required a flow of 1000 to 5000 GPM with head pressure varying from 40 to 120 meters. Ambient temperatures in winter (-55°C) needed to be addressed in the packaged design A minimum of 1000 GPM through the system must be maintained at

South Walker Creek CHPP

Situation A 3/2 AH Warman slurry pump ran at a constant 2950 rpm (regardless of process requirements) with a pressure-sustaining valve diverting excess water back to a water tank. Motor load was consistently above 31kW. This setup did not allow for adjustable speed; the valve wasted energy by pinching off excess water, but still strained

Exxon Mobil

Situation The left-over tar and coke from the petroleum extraction process are pumped to holding tanks. Due to the design of Exxon’s system, it is possible for the pumps to run dry when not enough tar is present in the strainer. This causes major damage to the impeller and pump casing.  There is a discharge valve to
