Fuel priming pump BNK-12TK

The rotary-type fuel priming pump BNK-12TK is designed to supply fuel from the vehicle tanks to the high-pressure fuel pump NK-10 Sb. 327-00-13 under pressure 0.5-07 kgf/cm2.

It consists of the following main parts: 1 - body; 2 - rotor; 3 - glass; 4 — rotor finger; 5 — rotor plate; 6 - filling valve; 7 - pressure reducing valve; 8—reducing valve spring; 9 - cover; 10 - nut; 11 - union nut; 12 — adjusting bolt; 13 - gasket. The pump ceases to produce rated fuel pressure parameters due to natural wear of parts or in the event of corrosion (rust) on the cup or rotor blades, which will lead to tearing on the cup.
