What is this in a mechanical pump?

As shown in the figure: What is this part of the pump? Next to the bearing? Why are there still three gaps? Thank you
This is GB812 \"Round Nut\", which should have 4 notches; it is used in combination with a retaining washer for round nuts, to secure rolling bearings.
There is a locknut along with a locking washer; tighten the locknut and secure it with the locking washer.
If it is a vertical pump, it can also prevent axial movement of the shaft
On corrosion-resistant pumps, it is used to remove the impeller; corrosion- and wear-resistant pumps also use it to adjust the impeller clearance.

This locknut should be a standard part, to be used in combination with a washers and a special hook tool.
Bearing round nut, used to secure bearings. To be used in conjunction with a retaining washer. The groove on the outer circle is provided for assembly purposes, to allow tools to be used for striking. The outer claw of the retaining washer fits into the outer groove of the round nut.
That locking gasket used in combination is commonly referred to as a \"turtle gasket\" around here.\ud83e\udd23\ud83e\udd23\ud83e\udd23
