Dy Horizontal Multistage Centrifugal Oil Pump

A heavy‑duty horizontal, single‑suction, multistage centrifugal pump engineered for reliable transfer of oils, oil products and clean liquids without solid particles. The DY series delivers high efficiency, long service life and straightforward maintenance, and can be configured for a wide range of industrial pumping duties by changing wetted materials, seals and bearing arrangements.

Key features

• Operating temperature range: -20 °C to 150 °C
• Maximum fluid viscosity: up to 120 cP
• Flow capacity (Q): 6.3 – 450 m3/h
• Head range: 50 – 660 m (medium/low pressure); 409 – 1,056 m (high pressure)
• Construction: horizontal, single‑suction, sectional multistage centrifugal pump
• Shaft seal options: flexible gland packing or mechanical seal
• Bearing options: rolling bearings with dry lubrication (standard); slip/sleeve bearings with thin lubrication for high‑pressure variants
• Materials: cast iron for medium/low pressure pumps; cast steel or stainless steel available for high‑pressure units and corrosive services

Applications

• Transfer of oil and oil products and other clean liquids with similar physical/chemical properties to water
• Hot water circulation and high head oil transfer duties
• Can be adapted for corrosive or mildly abrasive liquids by selecting appropriate pump materials, seals and cooling arrangements

Benefits for B2B buyers

• Wide performance envelope suitable for process, utility and transfer applications
• Multiple seal and bearing configurations to match duty and maintenance preferences
• Modular multistage design simplifies maintenance and stage configuration changes
• Material options enable use in higher‑pressure and corrosive environments

Ordering and selection notes

• Specify required flow and head, operating temperature, fluid viscosity and any corrosive/abrasive characteristics to select the correct stage count, materials and seal type
• High‑pressure models typically use sleeve (slip) bearings and upgraded materials; confirm lubrication and cooling requirements for continuous high‑head operation
• Provide the model code (e.g., DY25‑30*9) when requesting a quotation to ensure accurate configuration and spare parts identification.
