API 4# Frac & Cement plunger Pump Valve and Seat Assembly
Plunger:
hard surface-coated or flame-sprayed, long service life. Plungers
are used to pull fluid into the fluid end through the suction valve
and push it out through the discharge valve. They do it by
retracting from the fluid end to create volume in the fluid end
chamber and then extending back into the fluid end chamber to
displace volume and push the fluid out.
Valve & Seat:
forged alloy construction, deep carburized surface, greater fluid
flow and easy valve maintenance. Valves are used to direct the flow
through the fluid end and separate the suction side of the pump
from the discharge side. As the plunger is pulled back the pressure
in the fluid end drops causing the discharge valve to pull harder
onto the discharge valve seat and also causes the suction valve to
lift off its seat.
Pressure Packing:
The pressure packing creates a seal around the moving plunger to
contain the fluid being pumped. The packing arrangement consists of
several components that work together in order to achieve this. For
example,
HT400:Spacer Ring, Header Ring, Packing Ring, Female Adapter, Seal
Carrier, Seal Carrier O-ring, Packing Lube Seal
Tws600: Lantern Ring, Seal Ring, Pressure Ring, PKG adapter, Header
Ring, O-ring, Back-up, O-ring, Back-up, Wiper Ring
