Shijiazhuang Dongli Petroleum Machinery (DLSY) supplies replacement parts for the Aplex SC-35, a triplex piston pump in the HDD category. Factory data rates it at 1500 PSI max working pressure, 51 GPM max flow, 50 HP rated input power, 2 in stroke and 625 SPM rated speed; its three-plunger layout delivers smoother flow than duplex designs and it is positioned for intermittent duty rather than the continuous service of the MA series. We stock 68 items for this model — gaskets, shim gaskets, tapered roller bearing cones and cups, oil seals, O-rings and hardware.
FAQ
What are the factory ratings of the Aplex SC-35?
Factory data lists a max working pressure of 1500 PSI, max flow of 51 GPM, rated input power of 50 HP, a 2 in stroke length and a rated speed of 625 SPM.
Is the SC-35 suited to continuous operation?
It is designed as an intermittent-duty pump, positioned apart from the heavier MA series built for continuous 24/7 service. Match it to duties with regular rest intervals for the best service life.
What parts does DLSY stock for the SC-35?
We hold 68 distinct items: vellumoid and cylinder gaskets, shim gaskets in different thicknesses, tapered roller bearing cones and cups, oil seals, O-rings, machine screws, washers and lock washers.
How does the triplex layout affect performance?
With three plungers working in sequence, the SC-35 delivers a smoother flow output than duplex or single-plunger designs, which reduces pulsation stress on hoses and fittings.
Can DLSY export SC-35 parts to North America and overseas?
Yes. Canada and the United States are core markets and we ship to international oil & gas regions as well, under HS code 84139100 with standard export documentation.
