Advantages of DL Mining Pump Series
Enhanced Efficiency
Reliable pumps for the mining industry contribute to smoother operations, reducing bottlenecks and lowering operational costs. High-performance mining pumps are essential for ensuring that materials move through the mining process seamlessly, enhancing overall productivity.
Reduced Downtime
Durable pumps for the mining industry are less prone to breakdowns, which minimizes costly downtime and keeps operations on track. By investing in pumps with exceptional performance, mining companies can avoid the frequent maintenance and repairs that lead to delays.
Adaptability in Challenging Conditions
Mining is an environment known for its harsh conditions, with abrasive materials, fluctuating water levels, and heavy sediments. Pumps for challenging conditions are designed to meet these unique demands, providing reliable operation even in the most extreme situations. Reliable pumps for the mining industry are engineered specifically to withstand these rigors.
Oil and Gas Exploration and Services
Can be used for fracturing fluid blending and pumping assistance in well site services, fluid transfer in cementing operations, chemical injection in well stimulation, drilling mud circulation (especially suitable for water-based or light oil-based muds, for which the ball valve structure offers good adaptability), pipeline pressure testing, and oily wastewater treatment.
Mining and Mineral Processing
Suitable for mine dewatering, tailings transport, dust suppression sprays, slurry transfer in mineral processing plants (requiring appropriate fluid end configuration based on slurry abrasiveness), and as a pump or mud pump for core drilling equipment.
Industrial Cleaning and Maintenance
With its high flow rate and moderate pressure, it can efficiently perform tasks such as large equipment surface cleaning, heat exchanger tube bundle flushing, tank interior cleaning, and municipal sewer jetting.
Construction and Infrastructure
Provides power as a mud pump in horizontal directional drilling (HDD) construction, water supply for tunnel boring and large concrete structure curing, and grouting operations in geotechnical engineering.
Agriculture and Irrigation
Can be used for large-scale farmland irrigation, long-distance water transfer, and rinsing and disinfectant spraying operations in large farms.
Base alignment
The pump must be mounted on a rigid base (Skid) to prevent crankcase deformation caused by operational torque.
Rotation direction
This is a critical point that is often overlooked. The top of the pinion shaft (input shaft) must rotate away from the hydraulic end (pump head). Only then can the internal large gear properly scoop up the oil from the oil pan and propel it toward the crosshead slide rail.
NPSH (Net Positive Suction Head)
While a 2-inch suction inlet is advantageous, the feed line should be kept as short and straight as possible. FMC recommends that the NPSHa (available) should exceed the NPSHr (required) by 5 feet of water column. For slurry with a specific gravity greater than 1.0, the available NPSH value decreases.
Lubricant change: Change after 50 hours of initial operation, then every 100 hours or quarterly. Use SAE 30 non-clean oil.
Check the weep holes at the bottom of the pump body: Excessive dripping indicates the failure of the siphon.
Lubrication: Lubricate the plunger oil seal seat every year. Do not over-lubricate to avoid damage to the oil seal.
Valve system maintenance: The innovative 'Bean' design enables direct valve inspection via the top valve covers, eliminating the need to dismantle the entire hydraulic system and significantly reducing downtime.
