3 Series I Pump and Prep Pump

4 Prior to removing the head, rotate the flag on the top of the motor so the piston is fully retracted. Remove thumb nuts or Allen nuts using a 3/16” Allen wrench and slide off the SST head.

5 Remove inlet check valve holder with a 1/2” wrench and slide out SST check valve. Place SST check valve in new inlet holder noting the arrow on flow direction. Screw new inlet holder into the head and torque to 75 inch pounds.

6 Remove one Phillips head screw from aluminum or SST spacer

7 Hold pressure down on spacer while removing the second screw in order to keep from twisting and breaking the piston

8 Slide out the spring and then the ceramic or SST piston

9 Place small amount of grease on end of piston (May be SST or PEEK) and insert piston into the pump mechanism

10 Slide spring back over the piston

11 Reinstall the two Phillips head screws that secure the aluminum or SST spacer

12 Slide the head over the piston and insert the two 5/32” Allen nuts or thumb nuts Working from side to side, lightly snug the nuts. Once seated, if Allen head nuts, torque the nuts to 30 to 35 inch pounds.

30 Piston Replacement Retracted Manually rotate pulley until piston is in the retracted position. Having the piston in the retracted position decreases the chances the piston will break when removing the pump head. Not Retracted Front of Pump

31 Head Removal and Piston Replacement Remove two Allen nuts or thumb nuts Slide head off Remove Self-flush housingSlide washer spacer off

32 Head Removal and Piston Replacement Lift up piston from saddle UHPLC piston is black Clean piston with Scotch-Brite. Rinse and use compressed air to remove any residue. Assemble parts in reverse order. Torque nuts to 30 in/lbs or hand tighten thumb nuts Series II, III are clear or ceramic

47 Seal Replacement Outlet If the backup washer is still in the seal cavity, insert the flanged end of the Teflon tool into the head and pull straight out. To remove the seal, reinsert the flanged end of the Teflon tool into the head, press to the side and pull straight out and remove the old seal. Gently clean the head with the Scotch-bright pad to remove any residue. Also, clean the piston with the pad to be sure the piston surface is clean. Do not use any other device other than the Teflon tool to remove and install the seal. Using a different device my scratch the head rendering it useless. To insert the new seal, position the seal on other end of the insertion tool so the stainless spring is positioned out and visible to the eye. Position the insertion tool so the seal will be pressed into the head without crimping, rolling or damaging the side of the seal. Press the seal into the head until it is firmly seated in the bottom of the seal port in the head. Reinstall the backup washer. Gently slide the head onto the pump.

51 Prior to removing the head, rotate the flag on the top of the motor so the piston is fully retracted. Loosen two screws on the front of the head using 1/8” Allen wrench and slide head straight off Mighty Mini Seal Replacement

52 Insert flared end of Teflon removal tool into center of seal, press to one side and pull out.

53 Place new seal on opposite end of extraction tool with SST spring facing up.

54 Press seal straight in. Do not insert seal in at an angle.

55 Correct placement of seal PEEK spacer. Incorrect placement of spacer. Raised section is facing out. Raised section should be inserted inward to hold seal in place.

The measure of the resistance of a fluid to flow. What is Centipoise (cps)? Water is the standard by which all fluids are measured. Water is 1 70 Degrees F.

79 Ways to help pump higher viscosity fluids: Elevate the fluid Increase temperature of the fluid Pressurize vessel housing the fluid Replace inlet and outlet check valves with larger diameter check valves

81 Constant Flow: Typical pump configuration Most pumps are constant flow Pump delivers specified FLOW Does not take into account pressure If pressure readout – pulse dampener w/ transducer Max pressure limited to pressure of pulse dampener PEEK psi SST-6000 psi Constant Pressure: Typical pump configuration Pump delivers specified PRESSURE Does not take into account flow……sometimes? No pulse dampener, uses Transducer “T” assembly Some pumps can be set above 9000 psi

82 Pulse dampener w/ transducer (Constant Flow) Transducer “T” Assembly (Constant Pressure) PEEK Stainless Steel (SST)

83 Constant Pressure: Does not take into account flow……sometimes? Constant pressure pump can be set up to run constant flow. 1)Press “Mode” button until Ml/Min LED is lit 2)Set flow rate to desired rate 3)Press “Mode” button until Hi/Pr LED is lit 4)Set hi pressure to a number that you know it will not reach running at the desired flow rate 5)Press Start/Run The pump will run up to the set flow rate and stay there.
