DAB EUROINOX 50/506 Multistage Centrifugal Pump, Built Around a Stainless Wet End
The EUROINOX 50/506 M is DAB’s 1.36 HP multistage horizontal pump. It wires for 115V or 230V single phase, drawing 14.6 A on the low leg and 7.4 A on the high one. Technopolymer diffusers on an AISI 304 shaft move 2.6 to 31.7 gpm against 236 ft of head, or 116 psi at the discharge. The body is stainless steel, the mechanical seal carbon/ceramic, and the motor sits behind IP44 with an IP55 terminal board.
Running It as an Irrigation Booster Pump on Clean Water
Mount it on a level pad close to the reservoir, because the suction side is where these lose their prime. It self-primes only after the body has been filled, so leave a tee and a plug above the inlet before you tighten the last union. Nothing in the package senses pressure. You supply the switch, the tank or the controller, which is the trade-off against the packaged version of this pump. Feed it filtered water only, since grit chews the seal faster than anything else in a fertigation loop.
Key Features
- Dual-Voltage 115V/230V Motor: Drops onto a 120V bench feed or a 240V panel with no rewind, so the pump follows the room.
- 236 ft Maximum Head: Enough lift for a second-floor manifold or a long horizontal run with no booster downstream.
- Stainless Steel Wet End: Body, AISI 304 shaft and stainless adjustment rings hold up in the damp, salty air of a fertigation room.
- Self-Priming to 6 mm: Clears small air pockets on restart, which matters on a suction line that drains back between irrigation events.
- 26 ft Maximum Suction Depth: Pulls from a sunken cistern or an in-ground tank without dropping a submersible in it.
- Thermal and Current Overload Protection: Cuts the motor before a jammed impeller or a stalled start can cook the windings.
- 1-Inch NPT Ports: Threads straight to standard 1-inch PVC or brass on both the suction and discharge sides.
