Fluid End Parts

In the production process of fracturing pumps, the fluid end parts are the most easily damaged part of the entire equipment as the fluid end is working under high pressure constantly and even ultra-high and high-frequency alternating loads. Due to structural reasons, the service life of the wearing parts of the fluid end would be merely a few hundred hours, and the service cycle and maintenance cycle is comparatively short.

As the fluid end is the most costly and significant part of the complete frac equipment. It is important to extend fluid end working capacity and service life from the production and cost aspects. Properly assembling, applying, and safely handling the fluid end parts on the fluid end, would also contribute to service life. It is a prerequisite that all these frac pump fluid end components be used and maintained properly.

Tianyu Mfg supply and service offer an extensive line of fluid end parts to keep your equipment running well.

FAQ:What are the Most Easily Worn Parts on the Fluid End?

These fluid end parts are plunger, header ring, pressure ring, wiper ring, spacer, adapter, lantern ring, suction valve, dis valve, insert (suction), insert(discharge), seat(suction), seat( discharge) and valve spring.

FAQ:How Frequently Should these Frac Pump Fluid End Parts be Maintenanced and Replaced?

Daily preventative maintenance: inspecting plunger pump oil leak or fluid leak is necessary.

Weekly preventative maintenance: inspect valves, inserts, valve seats, springs, discharge and suction cover seals.

Monthly( or every 100 hours) preventative maintenance: inspecting all fluid end consumables.

Quarterly (or every 250 hours) preventative maintenance: inspecting the plungers and packing assembly fluid end expendables. All packing pressure rings and header rings need to be replaced.

Yearly(or every 250 hours) preventative maintenance: worn or corroded plungers, packing brass, valve covers, the suction valve stops, packing nuts, discharge flanges, discharge flange seals, suction manifold seals.

FAQ:Can SPM, HT and GD’s Fluid End Parts be Interchangeable With Each Other?

No, they can’t. Here enclosed three images showing BOM drawing of SPM/GD/HT400 brands’ fluid end parts, you can find that most of the frac pump components are named the same.  Nevertheless, all the different brand fluid ends service on the market possesses different types of frac fluid end components. The modifications to repair any part of a fluid end frac pump, or use of components not qualified, can lead to pump damage or failure.
