ESP motor shroud ratings and operating conditions.

The kit includes: intake module, shroud, centralizer, adapter, tailpipe crossover, P73x60-E crossover (for 60 mm tailpipe), shipping cap, shroud assembly kit, and an assembly / spares kit.

Service: well fluid (oil, produced water, associated gas). Fluid limits: density to 1400 kg/m3; produced-water pH 6.0-8.5; H2S to 0.001% (0.01 g/l); fluid temperature not above 135 C.

Nameplate example KETsN-130-01: KETsN = ESP motor shroud; 130 = nominal casing ID, mm; 01 = tabled variant.

Attached scans cover KETsN-130 and KETsN-150 variants, intake-module ratings on 1000 kg/m3 water, and OD / connection dimensions.

Scan / image text translation (original scan kept as attachment below):

KETsN-130 stack lengths vs ESP motor (PED-*-103). Upper / lower / mid = motor sections. L motor is with SPT-1.
