FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why are deep-well borehole submersible pump cables manufactured with a flat profile instead of round?
In standard 4-inch, 6-inch and 8-inch boreholes, the radial clearance between the submersible pump bowls/check-valve flanges and the steel or PVC well casing is often only 6 to 12 mm. A flat parallel cable has a minor thickness (H) roughly half the diameter of an equivalent round cable, sliding past the pump body without getting pinched or scraped during installation.
Why must drinking-water submersible cables use peroxide-cured EPDM instead of standard neoprene (H07RN-F) or PVC?
Standard polychloroprene (H07RN-F) and sulfur-cured rubbers leach organic accelerators, sulfur compounds and odour/taste into water and absorb moisture over multi-year deep immersion. Potable-grade peroxide-cured EPDM meets KTW-BWGL, WRAS (BS 6920), ACS and NSF/ANSI 61 hygiene limits with near-zero water uptake.
How are flat submersible cables spliced to the motor tail at the wellhead?
Flat submersible pump cables are joined using waterproof resin-potted splice kits or dual-wall adhesive-lined heat-shrink tubing over staggered crimp barrels, tested to 50 bar hydrostatic pressure.
What does the 'Nom. OD mm' column in the dimension table represent for a flat cable?
For flat cables, the primary clearance dimension is the minor flat thickness H (e.g. 5.8 mm on 3×2.5 mm²), while the full H × W cross-section (e.g. 5.8 × 13.5 mm) is listed in the adjacent column.
