康明斯公司正在提供两款新的排水泵，目标是建筑、石油和天然气、农业、采矿、水和废水应用。QSF4X4 和 QSF6X6 将提供完整的成品，用于各自的操作，并由康明斯 QSF2.8 Tier 4 Final 发动机提供动力。

QSF4X4 支持高达 1350 gpm 的流速和高达 135 英尺的扬程，而 QSF6X6 设计用于高达 1430 gpm 的中等流速和高达 104 英尺的扬程。

两者都是自吸式的，并能自动重新上浆。它们由重型铸铁制成，安装在一个完全可牵引的拖车上，便于运输。

为这些泵提供动力的2.8 L QSF2.8发动机可用于工业应用，功率为 74 hp，体积紧凑。高压共轨燃油喷射、废气涡轮增压器和全权限电子控制技术使发动机能够提供 221 lb.-ft 的峰值扭矩，并具有接近零的排放。雕刻的铸铁缸体确保了耐用性，重量轻至 507 磅。

该公司指出，新泵与康明斯远程信息处理服务兼容，有助于最大限度地提高可用性并最大限度地减少停机时间。

这两种型号均在北美销售，并将在 2 月 11 日至 15 日在佛罗里达州奥兰多举行的 ARA 展和 3 月 14 日至 18 日在拉斯维加斯举行的 ConExpo 上展出。

Cummins Inc. is making available two new dewatering pumps targeted to construction, oil & gas, agricultural, mining, water and wastewater applications. The QSF4X4 and QSF6X6 will be offered fully finished for use in their respective operations and powered by the Cummins QSF2.8 Tier 4 Final engine.

The QSF4X4 supports flow rates up to 1350 gpm and heads up to 135 ft., while the QSF6X6 is designed for moderate flow rates up to 1430 gpm and heads up to 104 ft.

Both are self-priming and re-prime automatically. Constructed from heavy-duty cast iron, they are built on a fully towable trailer for ease of transport.

The 2.8 L QSF2.8 engine powering the pumps is available for industrial applications at 74 hp in a compact envelope size. A high-pressure common rail fuel injection, wastegated turbocharger and full-authority electronic control technology enable the engine to deliver a peak torque of 221 lb.-ft. with near-zero emissions. A sculptured cast-iron block ensures durability with a low weight of 507 lbs.

The new pumps are compatible with the Cummins telematics service to help maximize availability and minimize downtime, the company noted.

Both models are available throughout North America and will be on display at the ARA Show in Orlando, Fla., February 11-15, and at ConExpo in Las Vegas, March 14-18.
