Interpump WS252 Triplex Plunger Pump (GP TS2021 Cross) - 5.6 GPM, 3625 PSI, 1450 RPM

Genuine Interpump WS252 triplex plunger pump: 5.6 GPM (21 L/min) at 3625 PSI (250 bar), 1450 RPM, 24mm solid shaft with key, 20mm solid ceramic plungers, 1/2" BSPP female inlet and 3/8" BSPP female outlet, 32 lb (14.5 kg); plan on 14 HP (10.3 kW) to run it at full pressure. General Pump sells this pump in the US as the TS2021, rated 3500 PSI at 5.6 GPM and 1450 RPM, so the WS252 matches it rating for rating. Karcher and Hotsy list the pump as 8.702-670.0 (Hotsy legacy number 102115G), and NorthStar also files the TS2021 under 8.702-669.0 and 5-2307. The WS252 replaces the 200-bar (2900 PSI) Interpump WS202 we stocked before: Interpump's parts lists show the same crankcase, crankshaft, connecting rods, 20mm plungers, seals and valves, so it drops in wherever a WS202 or TS2021 was fitted and takes the same repair kits (Kit 1 valves, Kit 2 and Kit 3 oil seals, Kit 28 and Kit 69 seal packings, Kit 7 head rings, Kit 10 packing retainers). Its manifold carries M24x1.5 fine-thread valve caps (Kit 4F), where the WS202 and TS2021 use M24x2 caps (Kit 4).
