Hypro D160 Diaphragm Kit

Hypro rebuild kit 9910-Kit1730 is the replacement diaphragm kit for the D160 diaphragm pump. Hypro recommends changing the diaphragms every 500 hours or three months, whichever comes first.

Kit1730 has been superseded by AR43257. 

The kit includes four replacement Desmopan diaphragms (9910-550085), eight replacement valve O-rings (9910-680070) and replacement accumulator diaphragm (9910-550190).

When rebuilding the pump diaphragms follow all factory torque specifications. Accumulator diaphragm should be set to 20% of pump operating pressure. Replacing diaphragms will require new oil. Replace with 30 weight non-detergent or Hypro pump oil (2160-0038).

Replacement o-ring (9910-Kit1908) and valve kits (9910-Kit2374) are also available for the D160 pump.
