Challenge: High-Cost, Time-Intensive Pump Overhaul

Westpower was contracted to overhaul two large Leistritz twin-screw pipeline pumps. We were asked to quote 19 days x 3 technicians per shift on a 24-hour schedule based on the client’s assessment of the scope of work.

Westpower’s Solution: Expert Field Service Backed by In-House Specialists

Trained and specialized in pumps, and backed by a technical team of applications specialists, design engineers, and experts in mechanical seals, lubrication, metallurgy and vibration, Westpower team delivered. The overhaul was completed in 7 days and the invoice was less than half of the estimate, saving $167,000.

The scope of work included bearings and mechanical seal changes, replacing coupling shim packs, annual preventative maintenance, and maintenance of the lube oil and barrier fluid systems flush.
