Gardner Denver recently announced the latest addition to their suite of frac and well service pumps. The GD 2500Q Heavy Duty Frame (HDF) quintuplex pump features a uniquely optimized power end frame designed to reduce operating stress, maximize frame reliability and extend pump service life.

The harsh operating conditions specific to hydraulic fracturing (“fracking”) demands the highest level of robustness and stability from a service pump. This is where Gardner Denver has focused their efforts with the new GD 2500Q. The pump has been upgraded with an increased frame thickness, allowing for larger, stronger welds. This has enhanced the structural integrity of the pump, thus extending service life expectation and reliability.

Other design upgrades with the new GD 2500Q include:

• A stronger support structure for the nose plate to reduce deflection around nose plate welds.
• Deep beveling around the outer main bearing plates, providing a deeper weld throat.
• Stronger bolt-on outer main bearing retainer to increase axial tolerances for improved gear timing (no more snap ring bearing retainer).

The GD 2500Q HDF comes with hardened clamp-type extension rods, alloy steel stay rods, and Gardner Denver hard-coated plungers. The pump also comes with Gardner Denver wing guided valves and seats and is available in either single or dual-bolted steel WECO style discharge flanges. The GD 2500Q features a Schedule 80 steel suction manifold with victaulic (mechanical grooved) coupling.

The GD 2500Q HDF contains five plungers with plunger sizes available in 95 mm to 171 mm (3.75 in to 6.75 in). The pump has a maximum RPM of 330 with a maximum displacement of 129 L/s (2044 gpm). The pump requires no alignments for suction covers and there are no special tooling requirements for installation, which also simplifies maintenance activities.
