Table 2.1: Gardner Denver TEE-BFB key performance indicators

Table 2.2: representative performance data (based on high-voltage configuration)

The following table shows the typical flow and pressure performance of TEE-BFB under different plunger sizes. The data is calculated based on 90% mechanical efficiency and 100% volumetric efficiency, which provides an accurate reference for your working condition matching.

Frame and crankshaft construction: the superiority of ductile iron

The reciprocating movement of the pump will produce violent vibration, which is the main cause of component fatigue and premature failure. In contrast to conventional welded steel structures, the TEE-BFB power end frame, crankshaft and connecting rods are made of high-strength Nodular Iron by precision casting.

The spheroidal graphite structure of nodular cast iron endows it with excellent vibration absorption capacity and fatigue resistance.

Drive train and bearings: for continuous heavy loads

The TEE-BFB is a compact and extremely durable construction with a sturdy eccentric shaft and monolithic ductile iron connecting rod. We have carefully selected bearing combinations for the power end: Tapered roller bearings for the main bearings, capable of withstanding both large radial and axial loads, and cast bronze bushings for the crank pin bearings

Lubrication system: comprehensive component protection

In order to ensure that the power end can be fully lubricated under any working conditions, TEE-BFB uses a dual pressure and splash lubrication system. The system not only provides basic lubrication for the internal parts by splashing, but also is equipped with independent oil pumps, the clean lubricating oil filtered by the filter core is accurately conveyed to the crosshead, the main bearing and other high-load key parts through the pressure pipeline. This design ensures continuous, clean oil film protection of the core components even under extreme conditions of low speed or high load, thus effectively preventing wear and extending the maintenance cycle.

Modular hydraulic end design: tailored for specific applications

One of the outstanding advantages of the TEE series pumps is their modular hydraulic end design. Depending on the pressure level and fluid medium, we offer a wide range of hydraulic end options, including cast aluminum bronze and cast Steel for low and medium pressures, and Block Steel for high pressure applications. The TEE-BFB model comes standard with the highest specification integral forged steel hydraulic cylinders, designed to withstand extreme pressures.

Autofrettage process: the core technology for high pressure durability

Tee-bfb's high-pressure forged steel hydraulic cylinders use an advanced Autofrettage process that is key to their superior fatigue life. During the manufacturing process, we apply ultra-high hydraulic pressure far beyond the operating pressure to each hydraulic cylinder, causing permanent plastic deformation of its inner wall. When the pressure is released, the outer elastic material forms a strong residual compressive stress on the inner layer.

Analysis of wearing parts-plunger: pioneer of straight-face wear

The plunger is the core moving part of the hydraulic end, and its material selection directly affects the performance and maintenance cycle of the pump. We provide a variety of high-performance plunger materials to adapt to different working conditions:

Wearing parts analysis-valve assembly: the heart of the hydraulic end

The performance of valve assembly (including valve body, valve seat and valve rubber) determines the efficiency and tightness of the pump. Tee-bfb valve assemblies are manufactured to API 7K for the highest quality and safety. We offer a variety of material combinations to cope with different fluid characteristics.
