Page 11: Outline
Outline The information such as characteristics, features and part names are described in this section. Introduction Pump structure & Operating principle The HRP series is a diaphragm metering pump which consists of a pump head, drive unit and control unit. A diaphragm is directly driven by electromag- netic force. -
Page 12: Features
Features 12/24VDC power voltage The HRP series powered by 12VDC or 24VDC offers the best fit to the built-in application. High resolution Digitally-controlled spm range is 0-720spm. The minimum flow of 0.055ml per shot offers a constant imperceptible injection. * The operation speed of the stop control type is always fixed to 720spm and is not vari- able. -

Page 24: Operation
Operation The pump becomes ready after pipework and wiring is com- pleted. This section describes pump operation and programming. Before operation Check the liquid level in the supply tank, tubing and wiring. And then perform degassing and flow rate adjustment before starting operation. Points to be checked Before operation, check if... -
Page 25: Degassing
Use of a Phillips screwdriver instead of a torque driver (a) Lightly tighten the pump head unit fixing screws until the sprig washer be- comes flat. (b) Further turn the screws clockwise 180 degrees. 180° Until spring washer becomes flat Degassing The gas needs to be expelled from the pump and tubing by degassing. - Page 26 Install an air vent valve or AVC check valve on piping for degassing. Follow the procedure below to conduct degassing in case neither valve is available. Connect a discharge tube and place the tube end in the supply tank or Outlet another container.

Page 27: Operation
Operation This pump is controlled by the external signal. Read through this section for proper operation. ■ Operation of the Pulse control type The input of the pulse signal controls the pump operation (stroke rate). The pump makes one shot per pulse synchronously. *The signal input is required to make operation after power activation for this type. -
Page 28: Operation Of The 1-5V Control Type
■ Operation of the 1-5V control type The input of 1-5VDC proportionally controls the pump operation (stroke rate). A stroke rate decreases to 0spm at 1VDC and increases to 720spm at 5VDC. *The signal input is required to make operation after power activation for this type. *An input voltage should be in between 1 to 5VDC and should not exceed the range. -
Page 29: Flow Rate Adjustment
Flow rate adjustment The flow rate is adjusted by the stroke rate. The stroke rate is indicated in spm (stroke per minutes). A stroke rate is determined by the number of external signals. Determine a suitable stroke rate, taking account of the pump operating condi- tion and liquid characteristics. -
Page 30: Maintenance
Maintenance This section describes troubleshooting, inspection, wear part replacement, exploded views and specifications. Important • Observe instructions in this manual for maintenance, inspection, disman- tlement and assembly.

Page 33: Wear Part Replacement
Wear part replacement For a long operation wear parts need to be replaced periodically. It is recommended that the following parts are always stocked for immediate replacement. Contact us or your nearest dealer for detail. Precautions • When dismantling the pump, pay attention to the residual liquid in the pump. -
Page 34: Before Replacement
Before replacement First release the pressure from the pump and discharge line. Otherwise, liquid may gush out. Stop the pump operation. Release the internal pressure. Open the air vent valve if it is installed. If not, see page 25. Check that liquid comes out from the air vent port and the internal pressure has been expelled. - Page 35 Turn the diaphragm anticlockwise to detach it from the plunger. NOTE Pay attention not to lose diaphragm spacers. Always apply a proper number of dia- phragm spacers. 0 or a few diaphragm spacers are inserted between the retainer and plunger for the adjustment of diaphragm location. Note that the number of diaphragm spacers varies with pump model.
