Pumps

 

STEP 2: Add quick disconnects and ball valve

We need to attach a ball valve on the pump output so that that flow speed can be controlled. Male quick disconnects are attached to allow our hoses to be easily connected/disconnected. 

We've oriented both disconnects to point horizontally to make hose connection/disconnection easier.

Like in previous instructions, wrap all threaded ends first with PTFE white teflon thread sealant tape to ensure a tight, leak-free fit. 

Once threaded, attach the ball valve and associated hardware to the input/output of the pumps are shown below. Both pumps use identical parts.  

Breakdown of the pump parts:

(A) Stainless steel male quick disconnect 1/2" MPT
(B) Stainless steel coupler 3/4" FPT x 1/2" FPT
(C) Pump with high temperature stainless steel housing (3/4" MPT inlet, 1/2" MPT outlet)
(D) Stainless steel street elbow 1/2" FPT x 1/2" MPT
(E) Stainless steel ball valve 1/2" full port

 

Tighten using a wrench until everything is tight. You cannot overtighten.
