Page 10 HMP-0567E Rev.7 (10/19) 5) Suction filter a) Be sure to install a suction filter on the suction side of the pump. b) Select a mesh size within the 100–200 range depending on the environment in which the unit has been installed and its operating conditions. c) Select a filter capacity that will be large enough to maintain proper operation in consideration of increased fluid viscosity in the wintertime as well as the possibility of filter clogging.
Page 11 HMP-0567E Rev.7 (11/19) f) It is recommended to use a rubber hose as the delivery pipe in order to reduce the vibration and noise produced by the unit, and to prevent excessive force being exerted on the pump. 8) Pressure specifications a) Definitions of "rated pressure"...
Page 12 HMP-0567E Rev.7 (12/19) 9) Shaft speed If the operating shaft speed is within the range shown in Table-3.9.1, the pump can be operated continuously. Table-3.9.1: Rated shaft speed ranges Rated shaft speed 1000—1800　min Allowable shaft speed of QT2* and QX2* are different from the above table. Please check with specification or external dimensions drawing of the pump.

Page 16 HMP-0567E Rev.7 (16/19) In general, a filter inspection should be conducted every one to three months. If a suction filter with a clogging indicator is used, be sure to clean or replace the filter element within the period in which the indicator is yellow. Startup after a filter inspection should be performed in accordance with the instructions given in Section 4.4.
