Ghost Shrimp Pump Parts and Instructions

Ghost Shrimp Pump Parts needed:  

A 30” to 36” long piece of 2” diameter ‘thin-walled’ PVC pipe.

A 36” to 42” long piece of 3/4” diameter ‘thick-walled’ pipe.

A 3/4″ 90-degree elbow or T-fitting.

A 2” end cap (with a 3/4” hole drilled in it).

TWO 3/4” end caps. One will need a 5/16” hole drilled in the center.      

A 5/16” stainless steel lock nut (and washer).

A 2” PVC Test Plug (the red plastic will need to be ground down to fit inside the 2” tube).

A 5/16” X 2” Stainless Steel bolt (to replace the standard 1 1/2” long bolt in the test plug).

A 5/16” stainless steel wing nut.

A small can of PVC ‘primer’ and PVC cement (glue).

 

Some assembly required:

NOTE: the long piece of 3/4” pipe should be no longer than the length of the 2” pipe.

So cut a 6” long piece off one end of the 3/4” pipe to use for your handle.

Glue one end of this 6” long pipe into the intact 3/4” end cap,

Glue the other end into the 3/4” elbow (or T).

Glue the longer 3/4” pipe into the bottom of the handle elbow (or T).

IMPORTANT: pass the 2” end cap up onto the long piece of 3/4” PVC.

IMPORTANT: pass the thread end of the 2” long 5/16” bolt out the end of the 3/4” end cap before gluing to the lower end of the 3/4” pipe.

Thread the washer and lock nut onto the 5/16” bolt and tighten (be careful not to over tighten).

Place the test plug on the end of the 5/16″ bolt and the wingnut after it (tighten by hand only).

The 2” pipe should slide over the test plug and into the end cap suspended on the handle.

I prefer to just push the long outer tube into the end cap near the handle instead of gluing it. This allows it to be quickly disassembled after use to rinse away all sand and saltwater. Also, I add a drop of 3-In-One oil to the end of the bolt and loosen the wing nut to allow the rubber O-ring to relax until needed again. The amount of pressure the wingnut exerts on the O-ring will squeeze it outward against the sides of the tube. So when the handle is pulled upward, it creates a vacuum which draws water and sand (and hopefully a ghost shrimp) up into the tube. The contents are dispelled off to one side and examined for a ghost shrimp simply by pushing the handle back down in the tube.
