FIELD SERVICE

3410 Goulds Refurbishment, United States & Peru

A miner, smelter and refiner of copper and molybdenum in the United States and Peru was experiencing pump problems and needed a timely solution. A Quadna service team evaluated the situation and performed repairs on a Goulds model 3410L 8x10-21 pump. Quadna quickly located and expedited the crucial parts and materials. The pump and rotating assembly were disassembled, a new shaft, sleeves and sleeve nuts were machined and the casing was weld-repaired. The newly repaired pump was delivered it to the jobsite and installed to ensure it was fully operational.

Block & Terrace Fountains, Colorado

The City of Denver tasked Quadna with the evaluation of the block and terrace fountains, designed by Lawrence Halprin and located in lower downtown Denver. Dedicated more than 25 years ago, the fountains at Skyline Park were shut down due to drought and other factors in early 2000.  Quadna was asked to remove dated equipment and complete the fountains’ restorations. The rework included upgrading the system controls, the installation of ITT/Goulds PumpSmart 200s and rehabilitation of the circulation and filtration systems.

VIT Line Shaft Upgrade/Retrofit, Colorado

A mining operation in Southwestern Colorado began an expansion process that required the increase in discharge pressure of their existing VIT Line Shaft pumps.  Each individual pump, originally supplied by Quadna, is 150 ft long and weighs 12,000 lbs.  Quadna extracted each of the three pumps one at a time, retrofitted them with new bearings in the bearing retainers and new bowl assemblies.  Their discharge heads were then cleaned and repainted before being set back into their prior positions.  Start-up and inspection was performed one pump at a time to maintain gold production levels and prevent downtime.

 

40,000-Pound, 29-Foot Long Vertical Pump Solution, Arizona

One of the nation's largest generators of electricity contacted Quadna to investigate a problem it was experiencing with a 78X54 WMCC vertical column 2B circ water pump. The 40,000-pound pump, driven by a 1750 horsepower, 505 revolutions parts per minute, 400-volt motor, was removed using a 70-ton crane. During the removal process, a faulty valve caused more than a foot of water to flow from the cooling tower. Quadna’s field team leader had the pump reinstalled, constructed a steel wall to divert the water into the sump and continued the removal. The 29-foot-long vertical pump was repaired and reinstalled without issue.

Integrated Multi-Pump Pregnant Solution System Upgrade, Colorado

Quadna developed a system to move golf-pregnant solution through carbon absorption tank trains using five client-preferred pumps to replace the existing 10 system pumps. The new pumps and the system innovations implemented reduce in-process carbon destruction and decrease transfer time by half.
