Yegong (Hebei Yegong Pump) Slurry Pumps and Flow Passage Parts

Yegong / Hebei Yegong Pump industrial slurry equipment: ZJE filter press feed pumps, 65ZJE-350 impellers, volutes, shaft sleeves, and wear parts.

Yegong ZJE slurry pumps for filter press feeding

Yegong / Hebei Yegong Pump ZJE slurry pumps are engineered specifically for filter press feeding duties. The hydraulic geometry delivers a steep performance curve: high volume flow during early cavity filling transitioning to high fluid pressure as the filter cake consolidates.

Volumetric slurry delivery rates spanning from 15 to 279 cubic meters per hour smoothly
Discharge fluid pressure heads reaching between 40 and 130 meters for deep filtration
Tailored hydraulic wet end profile optimized for chamber filling and solid dewatering
Direct coupled electric motor drive configurations supporting heavy industrial duty

Yegong 65ZJE-350 first and second stage impellers

Yegong / Hebei Yegong Pump first stage 65ZJE-350-6 and second stage 65ZJE-350-5 impellers are produced from high-chromium wear-resistant iron alloys. The hydraulic vane profiles handle high-density abrasive slurries while maintaining steady hydrodynamic efficiency over time.

Reinforced second stage impeller 65ZJE-350-5 engineered for final pressure generation
High chrome alloy metallurgy delivering superior resistance against abrasive slurry wear
Precision balanced rotating assembly reducing bearing vibration and shaft deflection

Yegong 65ZJE-350 spiral chambers and volutes

First stage 65ZJE-350-3 and second stage 65ZJE-350-4 volute spiral chambers form the fluid pressure path in Yegong / Hebei Yegong Pump machines. Heavy alloy wall thickness withstands abrasive slurry scouring in regions with high turbulent flow velocity and dynamic impingement.

Second stage volute body 65ZJE-350-4 built to sustain maximum cycle operating pressure
High chrome iron metallurgy preventing abrasive wall thinning and material wash out
Precision machined mating faces ensuring fluid tight sealing across operating ranges

Yegong 65ZJE-350 protective plates and wear liners

The 65ZJE-350-14 wear plate protects Yegong / Hebei Yegong Pump internal cavities from abrasive slurry impact. Positioned in the high-shear region adjacent to the impeller, it absorbs abrasive particle scouring and shields the heavy outer frame components from damage.

Defends internal housing walls against turbulent eddy scouring and slurry abrasion
Straightforward component replacement during scheduled pump maintenance intervals
Maintains accurate hydraulic clearance boundaries around rotating impeller faces

Yegong 65ZJE-350 shaft sleeves and packing gland assemblies

The shaft sealing arrangement in Yegong / Hebei Yegong Pump equipment features shaft sleeve 65ZJE-350-1, packing gland 65ZJE-350-12, stop ring 65ZJE-350-7, and sealing rings. The assembly prevents slurry leakage along the drive shaft and shields rotating components from wear.

Heat-treated shaft sleeve 65ZJE-350-1 with polished finish for minimal packing friction
Gland packing follower 65ZJE-350-12 distributing uniform compression around the shaft
Stop ring 65ZJE-350-7 and rear sealing ring 65ZJE-350-8 securing axial sleeve location
Dependable shaft sealing under elevated slurry backpressure protecting bearing units

Yegong 65ZJE-350 feed housings and inlet bodies

The 65ZJE-350-11 feed housing in Yegong / Hebei Yegong Pump machines delivers uniform slurry distribution into the first stage impeller eye. Robust iron structure attenuates hydraulic shock loads and dampens piping vibration throughout demanding industrial operating cycles.

Feed housing 65ZJE-350-11 contoured for streamlined slurry intake and minimal head loss
Heavy rigid iron body structure absorbing pipe expansion stresses and pulsation forces
Resilience against erosive turbulence when handling suspensions with coarse particles
Standard industrial flanged interfaces ensuring straightforward plant line integration

Filter press feeding operational cycles and 65ZJE-350 hydraulic curves

Dewatering industrial slurries using filter presses demands specialized hydraulic pressure profiles. During initial feeding stages when plate chambers remain empty, system flow resistance is low, requiring the Yegong / Hebei Yegong Pump unit to deliver maximum slurry volume rapidly.

As solid cakes accumulate against the filter media, hydraulic resistance rises steeply. The 65ZJE-350 slurry pump responds by automatically reducing volumetric discharge while multiplying output pressure to press the cake tightly.

This steep characteristic prevents hydraulic motor overload, eliminates flow separation, and produces dry compact filter cakes prior to plate opening.

High-chromium alloy metallurgy and wear protection for abrasive slurries

Pumping dense mineral slurries with sharp solid particles requires durable wear-resistant metallurgy. First stage 65ZJE-350-6 and second stage 65ZJE-350-5 impellers together with volute bodies 65ZJE-350-3/4 are molded from high-chromium white iron alloys.

The microstructural composition features hard chromium carbides embedded within a martensitic matrix. This material effectively resists micro-cutting and impact fatigue along vane edges when handling abrasive quartz, feldspar, and metallic concentrates.

Uniform metallurgical durability preserves hydraulic pumping efficiency across continuous plant operating campaigns.

Shaft sleeve assembly, packing gland adjustment, and sealing reliability

Drive shaft longevity in Yegong / Hebei Yegong Pump machines relies on the integrity of the rotating seal assembly. Replaceable shaft sleeve 65ZJE-350-1 is produced from alloy steel with hardened heat treatment and precision ground sealing lands.

The packing gland follower 65ZJE-350-12 applies uniform compression across graphite or PTFE packing rings. To prevent abrasive mineral grains from migrating along the sleeve, clean flush water is introduced at a pressure exceeding internal pump pressure.

Stop ring 65ZJE-350-7 and rear sealing ring 65ZJE-350-8 secure axial alignment without deflection.

Volute geometry inspection, eddy erosion defense, and wear plate renewal

Throughout heavy slurry service, the 65ZJE-350-3 and 65ZJE-350-4 spiral volutes experience dynamic wear near the internal cutwater tongue. Thick alloy walls absorb impingement wear from high-velocity particles without premature wall thinning.

During scheduled plant overhauls, technicians measure residual wall thickness and radial clearances around the impeller periphery. Wear plate 65ZJE-350-14 absorbs turbulent eddy impact adjacent to the suction eye.

Timely replacement of sacrificial wear plates protects outer structural frame components and prevents unexpected slurry leakage.

Cavitation mitigation, piping shock damping, and feed housing 65ZJE-350-11

Maintaining smooth non-cavitating slurry entry into the pump suction is essential for hydraulic reliability. The 65ZJE-350-11 feed housing features a streamlined intake contour that suppresses fluid eddies before slurry enters the first stage impeller eye.

Rigid iron structural thickness dampens hydraulic shock loads and mechanical vibration transmitted from heavy plant slurry pipelines. When air pockets enter or downstream valves actuate, the rigid housing prevents distortion of internal mounting registers.

Standardized flanges enable rapid leak-free integration with plant dewatering circuits.
