Specification Submersible Pump ER4-T

ER4-type submersible pump. Motor protection class IP68. Available with electric motors from 7.5kW up to 22kW power. Equipped with a large oil reservoir, double sealed (2 x mechanical seal). The ER4-T is designed according to industrial specifications with the inlet at the bottom side of the pump, whereas the ER4-T O is the submersible pump model with top-down suction. 

All ER4-type submersible pumps include sensors for leakage control as well as temperature probes. Connection and usage of the leakage sensor and the temperature probe is possible with special starters for submersible pumps (see page 47). Warranty is only effective when used in combination with these special starters. 

The basic unit is the bare pump. A special special lifting device with frontloader connector and forklift pockets is available for mobile use in different pits and tanks to transport, lift-up and lower down the pump. 

For stationary use equipment for 4 different layouts is available (according to the type of application):

ER4-T Installation A, Flexible Installation

• Pump on pedestal ring with hose connector 90° 
• Lift-out from and lowering down into the pit with a chain 

a complete unit consists of: basic pump + pedestal ring + hose connector 90°

ER4-T Installation B, Standard-Installation

• With sliding guide and discharge connector 
• Lift-out from and lowering down into the pit with a chain 
• When lowering down into the pit the pump connects automatically to the discharge pipe at the bottom of the pit. 

a complete unit consists of: basic pump + discharge connector B + guide bars according matching pit
depth + optionally hose, hose connector and wall duct

ER4-T Installation C, Installation with a sliding guide using a hoisting post

The pump can also be used as a jetter to stir up the slurry: Lift up the pump up with the winch at the hoisting post and turn it around. To get back to "pumping mode" simply lower the pump down again and recouple it onto the discharge connector. An alternative to the pedestal ring is a limit stop at the bottom of the hoisting post. 

a complete unit consists of: basic pump + pedestal ring + sliding guide + discharge connector

ER4-T Installation D, Installation In Lagoons

The pump is installed on a frame to be placed on the lagoon bottom. To prevent damages to the lagoon foil two old tires are filled up with concrete and mounted under the frame. The frame is equipped with a support for a wooden beam. 

a complete unit consists of: basic pump + frame D + upper support
