High-tonnage equipment forging. Advanced technology ensures forging and grain uniformity, effectively controls the content of harmful iron elements.
Single-piece forging and single-piece heat treatment ensure stable product performance with strength and toughness.
Optimize the internal structure design of the product to enhance its service life. (Slot type, lantern cover type, eccentric support type), Strengthen the internal structure to make it wear-resistant and pressure-resistant.
The main components, such as the valve body, valve seat, and plunger in the improved cavity, have their raw material designs optimized to extend their service life.
Multiple size options (52", 56", and 60") can be matched with various mainstream pump trucks on the market.
The various piston sizes (3.75", 4"up to 6") meet the requirements of different fracturing process designs.
The preferred stainless steel can achieve a lifespan that is over four times longer at only half the cost of alloy steel.

TWS2250 Fluid End outside dimensions

TWS2250 Stainless Steel Fluid End is a key component with excellent performance in all aspects.

The raw materials are high-quality stainless steel 17-4PH and 15-5PH. Although the cost is twice that of alloy steel, it can achieve more than 4 times the service life, with significant cost-effectiveness.

The production relies on high-tonnage German SIMATO equipment for forging. Advanced technology ensures forging ratio and grain homogenization. The iron content is ≤1. Combined with single-piece forging and heat treatment, it ensures stable product performance and excellent strength and toughness.

In terms of structural design, the inner cavity is optimized to be slot type, lamp cover type, eccentric bracket type, etc., which are wear-resistant and pressure-resistant after strengthening treatment. The raw material design of the main accessories, such as the valve body, valve seat, and plunger in the cavity, is improved to further extend the service life.

It has strong adaptability and is available in 52-inch, 56-inch, and 60-inch sizes, which can match all types of mainstream pump trucks; the plunger size ranges from 3.75 inches to 6 inches, which can meet the needs of different fracturing processes and is a reliable choice for fracturing operations.
