The centrifuge(CF) in the diagram is on the left.
connected to the CF with a close nipple(CN) is a 1/4" stainless steel ball valve(BV)
connected to the BV with a CN is a 1/4" Tee fitting
connected to the 1/4 Tee with a 1/4 to 3/8 and 3/8 to 1/2 and 1/2 to 3/4 bushings is a 3/4 Tee
connected to the 1/4 Tee with a CN is a BV that serves as flow control
connected to the 3/4 Tee is a 6" 3/4 nipple and the flux capacitor() shown in cross hatch.
connected to the 6" nipple is a 3/4 to 1/4 reducing coupling(RC)
connected to the RC with a CN is a Cross(Cx) fitting
connected to the Cx is a pressure gauge and the larger of the two Heating Elements(Ha)
connected to the Cx with another 6" nipple another T fitting
connected to the T is the smaller Heating Element(Hb) and a 6" 1/4 nipple with a cap. This becomes an accumulator.
inside Ha is a 3500 watt water heater element taking 220V
Inside Hb is a 1500 watt element taking 120V
The circles at the bottom of Ha and Hb are the input ports and are connected to the pump

The flux capacitor has screwed into it a 1/4 to 1/8 hex bushuing and a 6" 1/8 nipple with a cap. Inside the nipple is a thermocouple
