Single wide passage impeller enabling excellent solids handling (typically Ø30–100 mm).
Optimized impeller-volute match for wide BEP and low energy consumption.
Dynamic balancing ensures low vibration/noise and longer mechanical seal life.
Insulation Class F, designed for continuous S1 duty underwater.
Optional overload, leakage, over-temp, bearing temperature sensors & remote monitoring.
Auto-coupling rail system for quick lift-out maintenance and minimal downtime.
The motor drives a single-channel impeller to create a stable 3D flow passage. The large, smoothly curved
channel allows solids and fibers to pass through with the liquid, minimizing adhesion and entanglement between the impeller and volute, thereby reducing clogging risk and improving overall efficiency.
Lift stations, combined sewer networks, WWTP inlet/outlet.
Basements, parking lots, malls, hospitals, campuses.
Food, paper, textile, farming, slaughterhouses, chemicals.
Stormwater emergency, temporary bypass pumping.
With agitator option for light sediment/sludge resuspension.
> Note: Typical ranges; customization available. Refer to datasheet/selection for final values.

Ensure adequate submergence and inlet conditions.
DOL/Soft-starter/VFD per grid and control requirements.
Portable hose discharge or fixed auto-coupling rail system.
Upgrade materials/seals for abrasive, corrosive, or higher-temperature duties.
Guide Rail System:Quick lowering/lifting with reliable discharge coupling seal.
Electrical Protections:Equip with leakage, overload, over-temp, phase-loss protection.
Routine Checks:Check oil chamber, water ingress, insulation, vibration & bearing temps.
Wear Parts:Mechanical seal, bearings, O-rings, wear rings.
Optional cutter for heavy fibrous waste.**
Agitator for light sediment resuspension.**
Explosion-proof variant per local codes.**
VFD panels for constant pressure/flow and remote monitoring.

Q1: What is the maximum solids passage?
A1:Typically Ø30–100 mm depending on discharge size; larger passages can be customized.
Q2: Can it handle fibrous sewage?
A2:Yes. For heavy fibers, add a cutter kit** or choose vortex/low-speed large passage variants.
Q3: Is VFD control supported?
A3:Yes. Ensure motor insulation/cooling suitability and operate near the efficient zone.
Q4: How is sealing ensured?
A4:Dual mechanical seals** in oil chamber with leakage sensor; follow preventive maintenance intervals.
Q5: What about mildly corrosive or sandy media?
A5: Choose stainless/wear-resistant materials, hard-faced seals, and consider lower speed.
Q6: How to size power and head?**
A6: Select near the pump’s BEP on Q-H curves and verify motor margin and system losses.
