Main pump (1) Shim |
Shim (1) regulates the negative flow rate. Add shims or remove shims in order to obtain the correct negative flow rate.
Thickness of one shim ... 0.1 mm (0.004 inch)
One shim (1) will change the negative flow rate approximately 3 L/min (0.8 US gpm) at a negative flow control pressure of 2350 kPa (340 psi).
Note: Adding one shim (1) increases the negative flow rate. Removing one shim (1) decreases the negative flow rate.
