    Pump
Click For Summary
An electric bilge pump is needed that is compact, ideally 12v, and can operate with a switch rather than a float. The pump should have a hose input, be able to run dry and self-prime, and feature large 1/2" fittings to prevent clogging with debris. Diaphragm pumps are recommended over displacement or centrifugal types for handling debris-filled water. The user has had difficulty finding suitable options in hardware stores and on Amazon and plans to explore aquarium stores for alternatives. Suggestions for specific models or retailers are welcome.

Looking for an electric pump for my bilge.

I'm having some trouble finding a smallish pump that won't foul with debris.- 12v ideally
- no reason for a float, I'll operate it with a switch
- must input by hose, not mesh/grill

- must be able to run dry and self-prime
- fittings must be large - 1/2" so it won't get clogged with debris
- low flow - I'm not trying to drain a lake here
- not one of those huge 1/2HP things, I want something more portable - like the size of a shoe

I'll have a few feet of hose on input and output, so I can put the ends where I need them.

Apparently, diaphragm pumps are better than displacement or centrifugal pumps for debris-filled water

I've looked through hardware stores and Amazon but very little joy. I'm going to start looking at aquarium stores.

Just wondered if anyone had any other suggestions.

My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett system is the current record measurement standard to place in a juxtaposition with) I would use some sight glass plumbed into the side of the tank to get the change in height so that I can multiply by the tank cross-section. Simple Idea. But... Is there a simple mechanical way to amplify the height in the sight glass to increase measurement precision...
