MPI™ Medium Pressure Products Air and Hand Pump: Setup and Preset Instructional Manual

MPI™ Overview Advanced Features The MPI™ Presetting Instruction Manual documents the proper installation procedures for the MPI™ tube system. Parker MPI™ Fittings can be assembled either manually or by using hydraulic presetting equipment. This manual provides step by step instructions to successfully preset each type of tubing approved for use with MPI™ fittings using either manual or air driven presetting equipment. Every MPI™ Fitting has the features shown below: MPI™ Fittings Pressure Ratings 3. Longer thread area for improved resistance to pressure and load on the ferrules. Parker Hannifin...

MPI™ Air Pump Kit - Setup Step 1. Attach the Air Pump to a clean air supply of 60-120 psi and 9 scfm. Attach pressure gauge to air pump by pushing quick coupling on to the nipple and tightening the collar gently until it stops. Quick Coupling Pump Outlet Pressure Adjustment Set pump preset pressure as follows. Identify the preset pressure for the preset head size (small or large), MPI™ fitting size and tube material from Tables 1 and 2. Remove the small black plastic cap on the swivel post and adjust the pump relief valve screw by inserting the Tee handle Allen wrench. Rotate the screw until...

Pump Pressure Adjustment Screw is located inside Nut TA B L E O F C O N T E N T S Relieve pump pressure by pressing the pedal down on the opposite side. Activate the pump again to check the preset pressure and then relieve the pressure again. After the gauge reads 0, unscrew the collar and remove the gauge by pulling straight out. Press to Activate Pump Press to Relieve Pump Pressure Attach the preset head to the Air Pump by pushing quick coupling on to the nipple and tightening the collar gently until it stops.

Rotate the Preset Head to point left, right, or up (depending on the desired angle of use) and the ram should rest flat against the pad. Preset Head Angle Left Preset Head Angle Up Insert preset body die into the head with the tapered body seat pointing out. If using the 9 MPI BODY DIE with the LARGE MPI PRESET ASSEMBLY refer to the additional instructions on Page 5. Tapered Body Seat Preset Head Angle Right Body Die Drops into Preset Head Screw the nut die into the preset head until it bottoms firmly against the bottom using the nut die handle. The face of the nut die should be approximately...

MPI™ Air Pump Kit - Pre-Setting Square cut the end of the tube and remove burrs from tube OD and ID. Slide nut and ferrules onto the tube with tapered end of ferrules pointed toward the end of the tube. (proper sequence is nut, short back ferrule and then longer front ferrule) Front Ferrule Back Ferrule Hold nut and ferrules on the tube while inserting the tube into the head and seat the end of the tube against the tube stop in the body die. Finger tighten (do not wrench) the nut into the nut die until the hex almost bottoms against the nut die. Leaving the nut approximately 1/4 turn from the...

Ensure tube is against body die stop and depress pump pedal until you hear the change in pump speed. Continue to depress pedal for at least 5 seconds. Pump speed should not slow sufficiently at the end of preset that individual strokes can be counted. (A) Relieve pressure by pushing down on the opposite side of the pedal and remove nut/ferrule assembly from the head by rotating the nut out. This should be easily done by hand without the use of a wrench. Inspect the preset nut/ferrule assembly to insure that the nut rotates easily, the ferrules are seated firmly on the tube (they do not rotate),...

MPI™ Hand Pump Kit - Setup Based upon the MPI™ fitting size and tube material select the proper preset head size and presetting pressure from Tables 1 and 2. Refer to Pages 15 and 16 for additional presetting requirements for Cone & Thread tubing and Heavy Wall Annealed 316 tubing.

Relieve the reservoir pressure on the pump by rotating the cap approximately 1/4 turn counter clockwise to the “vent” position. Remember to close the cap before transporting the pump or hydraulic fluid can leak from the reservoir. Due to the small volume of fluid used in presetting, the pump can be used with the vent cap in the closed position, but it still should be vented and closed occasionally to relieve pressure due to temperature changes, etc. Sometimes air can become trapped in the hydraulic system which can cause longer preset times and a jerky preset motion. To bleed the air, close the...
