Water Treatment
Industrial pump solutions for clean water, process water, circulation, transfer and selected wastewater duties, with configuration based on flow, head, medium and installation conditions.
Recommended Equipment
Centrifugal Pump
16 sub-series for water, wastewater, chemicals and multistage.
Submerged Pump
Vertical submerged centrifugal, tank-bottom installation.
Pipeline Circulation Pump
ISG / GDL inline for HVAC, hot water and industrial loops.
Chemical Pump
IH stainless or IHF PTFE-lined for acids, alkalis and corrosive media.
Key Selection Considerations
- Required flow and head — The centrifugal series covers 0.75–10,000 m³/h at 2–1,800 m head and 0.18–1,120 kW. The duty point follows from the required throughput and the system curve.
- Water quality and solids content — The nature and concentration of solids determine whether a standard centrifugal arrangement applies or whether a different configuration should be reviewed.
- Open-tank or pipeline installation — For tanks and sumps, the submerged series covers 2–600 m³/h at 8–100 m head, with immersion depth of 0.5–3 m or custom.
- Corrosion and material requirements — Where the water or process liquid is chemically active, the IH stainless and IHF PTFE-lined chemical series apply, covering 3.5–400 m³/h at 4.5–125 m head.
- Circulation duty in closed loops — The pipeline series covers 1.5–1600 m³/h at 2–230 m head and 0.18–250 kW for HVAC, hot water and industrial loops.
- Installation conditions and duty cycle — Suction conditions, available space, operating hours and power supply should be confirmed before the configuration is fixed.
Engineering Approach
The duty point is taken from the required throughput and the system curve, while water quality, solids content and installation type are reviewed alongside it, because they determine which arrangement applies. To raise a technical recommendation, send flow and head, water quality and solids content, liquid temperature, installation type, suction conditions, operating hours and power supply.
Frequently Asked Questions
How do I select a water treatment pump?
Start with flow rate, required head, fluid temperature, water quality, solids content, suction conditions, installation type and operating hours.
Are submerged pumps suitable for wastewater?
Submerged pumps can be considered for tank and sump applications. The pump should be selected according to solids, liquid properties, depth, flow and head.
What flow rate is available for water transfer?
The centrifugal series covers 0.75–10,000 m³/h at 2–1,800 m head, with motor power from 0.18 to 250 kW.
What immersion depth do submerged pumps support?
The submerged series supports immersion depths of 0.5–3 m as standard, with custom depths available. The actual depth should be confirmed against the tank or sump arrangement.
Are corrosion-resistant pumps available for process water?
The IH stainless and IHF PTFE-lined chemical series address corrosive media, covering 3.5–400 m³/h at 4.5–125 m head. Compatibility should be confirmed against the water chemistry.
What information is needed for a wastewater duty?
Flow rate, required head, solids content, liquid properties, temperature, installation type, suction conditions and operating hours.
