The SPM TWS 600s (TWS600S) is a well service pump whose power frame is CNC precision-welded from high-strength steel plate — typically T1 steel to ASTM A514 under aftermarket and manufacturing standards — then precision-machined to hold coaxiality between the crankshaft bore and crosshead slide bore, minimizing wear on moving parts. Factory data rates it to 21600 PSI maximum working pressure, 124 GPM maximum flow and 100 SPM. DLSY stocks 227 items: fluid cylinders, valve assemblies, crankshaft and connecting rod/crosshead assemblies, gear reducer lube assemblies and filters, exported under HS code 84139100.
FAQ
What replacement parts does DLSY stock for the SPM TWS 600s?
We stock 227 distinct items for the TWS 600s (TWS600S), including fluid cylinders, the fluid end with 3.50 two-piece covers, valve assemblies, crankshaft and crankshaft assemblies, connecting rod/crosshead assemblies, gear reducer lube assemblies, transmission oil filters and O-rings.
What pressures and flows can the TWS 600s deliver?
Per the factory data at the rated 100 SPM, output ranges from 38 GPM at up to 21600 PSI with the smallest fluid-end bore to 124 GPM at up to 6667 PSI with the largest — intermediate ratings include 46 GPM at 17851 PSI, 55 GPM at 15000 PSI, 75 GPM at 11020 PSI and 98 GPM at 8438 PSI.
What is the maximum working pressure of the SPM TWS 600s?
The factory-rated maximum working pressure is 21600 PSI, and maximum flow is 124 GPM, at a rated speed of 100 SPM.
How is the TWS 600s power frame built?
Rather than a casting, the frame is welded from high-strength steel plate — typically T1 steel (ASTM A514) per aftermarket and manufacturing standards — using CNC precision welding followed by precision machining to ensure coaxiality between the crankshaft hole and the crosshead slide hole, which minimizes wear on moving parts.
Do you export SPM TWS 600s parts internationally?
Yes. We ship to Canada, the United States and other international oil & gas markets under HS code 84139100 with full export documentation.
