A hydraulic diaphragm pump keeps the process liquid on the diaphragm and the drive oil behind it. Use this list when the pressure end on the card is what the line needs.
LANGO GT sits in this series, and its card also offers a packed-plunger wet end. Confirm the head on the quote. Do not read the maximum flow and the maximum pressure as one point.
