Submersible drainage pump J 12

Name: Submersible drainage pump J 12
Brand: Sulzer

Low-weight and compact design

The low weight and compact design of the submersible drainage pump J 12 ensure convenient transport, handling, and installation. The pump is ideal for pumping water and dirty water mixed with light abrasives. 50 Hz: head max 15 meters, flow max 9 l/s. 60 Hz: head max 18.5 meters (61 feet), flow max 8.5 l/s (135 gpm).

Main benefits

Plug-and-pump installation without having to worry about overheating.
Reliable, trouble-free operation also at low water levels.
High wear resistance ensures years of cost-efficient pumping.
Serviceability with modular design.

Benefits

Plug-and-pump installation

Plug in without having to worry about overheating. Built-in thermal protection protects the motor from overheating.

Wear resistance

One investment for years of cost-efficient pumping. Impeller in high chrome alloy steel ensures a long lifetime and high efficiency.

Reliable operation - minimizes maintenance time

Double outer casing and good heat convection enable the pump to operate continuously at low levels or even run dry without damaging the motor.

Serviceability

Save time and money with easy on-site service. Modular design lowers the overall service costs. By removing the top cover of the pump, you can easily check the electrical junction box. Environmentally safe white oil is used in the oil casing for easy inspection of seal conditions.
