Product Overview
Analyzing internal fluid velocity paths reveals the true operational efficiency of modern water management systems. Built around precision flow parameters, the Grundfos SE1.50.65.40.A.Ex.2.50B.B operates as a heavy-duty non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water, and unscreened raw sewage.
By incorporating an optimized configuration, the internal volute guarantees the unimpeded passage of suspended heavy media. Its ultra-dense exterior framework deflects the violent physical shocks commonly experienced during rapid flow state changes, shielding sensitive electromechanical elements from continuous exposure to abrasive liquid contaminants.
Thermodynamic stability is governed by the revolutionary S-TUBE impeller structure, actively propelling dense fluids without jamming. Supported by a 4 kW drive connected directly to a 3-phase 415v infrastructure, the equipment produces an outstanding maximum head of approximately 24.8 m alongside an approximate flow volume of 1464 L/Min through 65 mm ports.
Recognizing the critical nature of commercial facility uptime, engineers integrated a liquidless, maintenance-free cooling network for dry or submerged installations. An advanced stainless-steel clamp assembling protocol allows technicians to detach the primary motor effortlessly, avoiding the extended delays associated with complex industrial toolsets.
Features
- Boasts a massive total structural component weight measuring exactly 138 kg for supreme operational vibration dampening.
- Officially certified with a strict Ex db eb h mb IIB T3,T4 Gb explosion-proof safety rating for hazardous zones.
- Reliably processes dynamic internal liquid medium temperatures actively ranging between 10 and 40 °C.
- Engineered with a specialized Star-delta starting method to perfectly manage intense electrical load spikes.
- Designed to aggressively sustain a maximum operating environmental pressure measuring exactly 6 bar.
- Safely supports continuous deployments at a maximum completely submerged installation depth of 7 m.
- Provides superior IP68 grade ingress protection to secure the internal motor against fluid penetration.

To maintain vault balance under surge, what peak volumetric rate is discharged?
Displacing municipal effluent, Grundfos SE1.50.65.40.A.Ex.2.50B.B sustains a peak volumetric flow of 1464 L/Min.
Evaluating high-pressure discharge parameters, what maximum head does this pump generate?
Hydraulic delivery curves confirm SE1.50.65.40.A.Ex.2.50B.B reaches an elevation of 24.8 m.
Regarding motor electrical ratings, what motor output rating, line voltage parameters, and full-load current draw support this pump?
Operating current benchmarks for SE1-50-65-40-A-Ex-2-50B-B indicate a 8.2 Amps draw from a 4 kW motor on a three-phase 415 V feed.
To sustain prolonged station drainage, how does the tube runner design maintain open fluid pathways in deep vaults?
Operational fluid corridors in SE1 50 65 40 A Ex 2 50B B accommodate 50 mm spherical solids using a durable Open S-tube runner.
Simplifying submerged maintenance, what physical guide rail system allows submersible servicing without chamber dewatering?
Tight hydraulic coupling is established when SE1/50/65/40/A/Ex/2/50B/B seats onto the submerged auto-coupling pedestal in the sump.
