The Short Version
Sized to the bore, not to a catalogue number.
Pump specification is set by head and required flow, not by horsepower alone. Two farms with the same rating and different static water levels need different pumps and different arrays — which is why the range carries twenty-three models rather than six, several of them at the same horsepower with quite different head and flow.
Stainless steel 304 throughout
Wet end, motor casing and shaft. The parts that sit in water are the parts that decide service life.
NSK bearings
Specified by name on the datasheet, which is unusual and worth having.
Heads to 180 m
Deep bores are covered without going to an AC pump behind an inverter.
Flows to 22 m³/h
Large-flow models for channel irrigation as well as high-head models for deep bores.
Surface and submersible
Open wells, sumps and tanks as well as bores.
Maintenance-free
No routine service schedule, in a location where a service visit is a lost irrigation cycle.
Applications
Where this range is specified
Irrigation
Channel and drip feeding from bore or open well.
Dairy
Washdown, chilling and stock water.
Cold storage
On-farm storage with a continuous daytime load.
Community schemes
Cluster pumping under state programmes.

How do I choose between models at the same horsepower?
By head and flow, which is exactly why they differ. The IC 4-13.0-60 and IC 4-9.0-85 are both 2 HP: one moves 13 m³/h to 60 m, the other 9 m³/h to 85 m. Send bore depth, static water level and daily requirement.
What water can these handle?
Non-corrosive water with sand content no more than 0.1% by volume and particle size under 0.2 mm. Sandy bores need a different specification.
Surface or submersible?
Submersible for bores. Surface for open wells, sumps and tanks where the pump can sit above the water.
What array voltage do they need?
It varies by model, from 30–40 V on the smallest up to 480–610 V Vmp on the 7.5 HP units. Each model states its own requirement.
