Page 2: Safety Precautions
WARNING: USE OF THIS PRODUCT FOR ANY PURPOSES OTHER THAN ITS ORIGINAL INTENT, ABUSE OF THE PRODUCT, AND/OR MODIFICATION TO THE ORIGINAL PRODUCT IS STRICTLY PROHIBITED BY CDS-JOHN BLUE COMPANY. CDS-JOHN BLUE COMPANY RESERVES THE RIGHT TO DENY WARRANTY OR LIABILITY CLAIMS IN ANY/ALL SITUATIONS INVOLVING MISUSE, ABUSE OR MODIFICATION. - Page 3 INSTALLATION AND GENERAL SAFETY INFORMATION Always mount pump with oil sight tube in upright position. 2) Proper selection of type and size hose is vital to good performance: - Diameter of inlet hose should be at least that of the pump inlet hose barb or greater. - Use only hoses rated for maximum pressure rating of the pump. 3) Use of a pressure relief device on the discharge side of pump is required to prevent damage from pressure build up if the discharge is closed or blocked while the power source is still running.

Page 4: Suction Head
- Check to make sure that the inlet, discharge and by-pass hoses have the correct diameter, i.e. never smaller than the union on the pump. The hoses should not be crimped and the hose clamps should be sized for hose diameter. - Prevent any hose restrictions and be sure connections are tight to prevent air entering, since these conditions will compromise pump performance. - If pumping from a tank, check to make sure that the control unit by-pass line is not too close to the inlet line. Make sure that it does not create turbulence inside the tank. - Check air pressure in the pulsation damper. It should be kept within specs given in the Chart on the Service Manual. - The pressure regulator lever should be turned downward. Whenever the by-pass jet is used, the pressure adjustment lever must be turned in the down position so that the pressure is zero. - Check to make sure the strainer is clean. Be sure the cartridge is reinstalled and tightened to assure no suction leak. - Check for leaks. Suction Head Do not use suction head for filling the tank. Avoid suction head higher than 10 feet. In this case, some troubles may occur in the pump parts. Operation Instructions - Start pump and let run for approximately one minute at zero pressure to facilitate priming. - Page 5 Coupling to Agricultural Machinery 1) Check that the PTO of the machine does not exceed the max rpm shown on the pump plate. 2) If the PTO is synchronized with the motor speed, consult the service manual to get gear number and rpm corresponding to the max pump rotation speed. 3) When the rpm of the PTO is higher than the max speed, use the suggested reduction gear. 4) Disconnect the PTO when moving with pump out of service; if that is impossible, then disengagement should be provided. 5) Disconnect the PTO when changing direction. Coupling to electric motors and gasoline engines For direct coupling always use the suggested reduction gear.

Page 6: Diaphragm Replacement
2) Diaphragm Replacement - Drain the oil from the pump by removing cap under the crankcase. Rotate the shaft to remove excess oil. - Remove the pump heads one by one. - Use a hex wrench to remove the diaphragm locknut: remove the nut, retaining washer, diaphragm and support washer. - If you removed the piston sleeves, replace them one at a time in their previous position (best mark them when removing). - Insert the new diaphragm on the piston and install it with its nut. Use these tightening torques. • 10 mm.=36 ft.-lbs. • 12 mm.=50 ft.-lbs. • 12 mm.=72 ft.-lbs. The diaphragms should be replaced with the piston at its bottom DP and the edges inserted perfectly into the groove all the way around. - Page 7 DP-74.1 And DP-74.1-GRI PUMP DIMENSIONS...
