Abstract
Some particular preferred embodiments relate to the field of pumping stations for sewage and wastewater with submersible pumps mounted in the bottom of the wells. To allow easy cleaning and maintenance of the pumps without getting in contact with the dirty water the solution is a system for easy lifting of the pump out of the well and lowering the pump again with an auto coupling.
Claims26
A pump support comprising:
- a base part having a lower end and an upper end, said base part comprising an end face;
- and
- a guide claw adapted for carrying a pump and being configured for releasably arranging the pump on the base part at the end face, the guide claw comprising a first guide member, wherein the base part comprises:
- a lower support part at the lower end, the lower support part being configured to non-resiliantly support the pump in a longitudinal direction towards the base part and in a vertical direction towards the lower end;
- and
- an upper support part having a support surface at the upper end configured to receive said first guide member and supporting said first guide member in an abutting engagement with a resilient element positioned in between the upper support part and the first guide member, so that with gravity acting on the pump, the guide claw is resiliently supported at the support surface of the upper support part.

A method of providing a pump support comprising:
- a base part having a lower end and an upper end, said base part comprising an end face;
- a guide claw adapted for carrying a pump and being configured for releasably arranging the pump on the base part at the end face, the guide claw comprising a first guide member, wherein the base part comprises:
- a lower support part at the lower end, the lower support part being configured to non-resiliantly support the pump in a longitudinal direction towards the base part and in a vertical direction towards the lower end;
- and an upper support part having a support surface at the upper end configured to receive said first guide member and supporting said first guide member in an abutting engagement with a resilient element positioned in between the upper support part and the first guide member, so that with gravity acting on the pump, the guide claw is resiliently supported at the support surface of the upper support part, wherein the base part is mounted on a pump support carrying member, the method comprising the steps of:
- providing a pump with the guide claw;
- and
- lowering said guide claw toward the base part to provide that the lower support part has received and support said second guide member, and the upper support part has received said first guide member with a resilient element in between the upper support part and the first guide member.

A method of dismantling a pump provided with a guide claw from a base part of a pump support comprising:
- a base part having a lower end and an upper end, said base part comprising an end face;
- a guide claw adapted for carrying a pump and being configured for releasably arranging the pump on the base part at the end face, the guide claw comprising a first guide member, wherein the base part comprises:
- a lower support part at the lower end, the lower support part being configured to non-resiliantly support the pump in a longitudinal direction towards the base part and in a vertical direction towards the lower end;
- and an upper support part having a support surface at the upper end configured to receive said first guide member and supporting said first guide member in an abutting engagement with a resilient element positioned in between the upper support part and the first guide member, so that with gravity acting on the pump, the guide claw is resiliently supported at the support surface of the upper support part, the method comprising:
- raising said guide claw away from the base part.
