1. Principles of operation

There are two diaphragms fixed to the center rod, one at each end. When compressed air is supplied to air chamber b (right side, see Fig.1.1), the center rod moves to the right, the material in material chamber B is pushed out, and at the same time material is sucked into material chamber A. When the center rod is moved full-stroke to the right, the air switch valve is switched, compressed air is sent to air chamber a (left side, see Fig.1.2), and the center rod moves to the left. The material in material chamber A is pushed out, and at the same time material is sucked into material chamber B. Through repetition of this operation, material is repeatedly taken in and discharged out.

2. Tools, etc.

2.1 General tools ∙Socket wrenches 13mm ∙Open-end wrenches 13mm, 21mm ∙Pliers

2.2 Special tools (sold separately)

∙Accessory tool (included) ∙Sleeve remover (sold separately) Purpose: Removing the cap. Purpose: For removing sleeves

2.3 Misc. ∙ Assembly oil Turbine oil none addition class 1 (equivalent to ISO VG32 grade) ∙ Nuts M8 × 1.25 ∙ Grease Urea grease grade (NLGI) No.2

Tightening torque for manifold retainer DDS-10 □ 8 N•m

< NOTE >

• Make sure there is no dust on the seal surface and the seal is not damaged.

• Replace the PTFE O-ring regardless of its condition.


5. Diaphragm and Center rod

5.1 Removal

• Remove the ball and valve seat. (see, Fig. 4.1) • Remove the 4 retainer nuts from the out chamber, and

remove the out chamber. [Fig.5.1]

• Remove the center disk from one side. [Fig.5.2] • After the center disk (outside) has been removed, remove

the diaphragm and the center disk (inside). • Remove the center disk and center rod from the opposite

side of the main body.

<NOTE> • When the diaphragms are removed, the main body is

separated 2 pieces. For easy work, leave bolts fastened temporarily before remove the diaphragms.

• Remove the center disk and diaphragm from the opposite side using the double nut. [Fig.5.3]

<NOTE> • When the diaphragms are removed, the main body is

separated 2 pieces. For easy work, leave the tie rods or bolts fastened temporarily before remove the diaphragms.

• Be careful not to scratch or score the center rod.

• C-Spool Valve Assembly and Sleeve Assembly must be Replaced complete set. Unable to replace individual component.



<NOTE> • Make sure there is no dust on the seal surface and it is not

damaged.

8. Retightening of Tie rods

• The torque should be applied on the occasion of

(1) Right before the pump to use. (2) There are any leaks of material on daily inspecting a pump.
