Product Overview
▔▔Steimel Pump is a heavy-duty, high-efficiency positive displacement gear pump series designed by Gebr. Steimel GmbH for demanding industrial lubrication, fluid transfer, and precision hydraulic control applications. Positioned as a premium industrial-grade gear and rotary pump line, the Steimel Pump series-including popular models such as the SF, TF, and BKM lines-delivers consistent volumetric efficiency, low noise emissions, and exceptional longevity. It is engineered specifically for high-viscosity liquid transport, forced lubrication circuits, cooling systems, and critical hydraulic power units across heavy manufacturing and marine environments.

Configuration Options
▔▔- Structural Design: Foot-mounted (horizontal/vertical) or flange-mounted (SAE/ISO standard flanges). Built-in pressure relief valve or bypass valve options available.
- Control Methods: Constant-speed drive, variable frequency drive (VFD) speed control, or mechanical flow regulation.
- Feedback & Monitoring Options: Integrated port for pressure transducer installation, temperature sensor wells, and visual/electronic clogging indicators.
- Flow Rate Adjustments: Fixed displacement per revolution; flow controlled via drive motor RPM or VFD integration.
- Interface & Porting: Threaded ports (BSP / NPT) or standard ANSI / DIN / SAE flanged connections.
- Electrical Configurations: ATEX-certified explosion-proof motors, IP55 / IP65 enclosure standards, custom voltage/frequency configurations (220V/380V/440V/660V, 50Hz/60Hz).
Key Materials and Components
▔▔
- Pump Housing & Covers: High-density Cast Iron (EN-GJL-250) or Ductile Iron (EN-GJS-400-15) for high wear resistance and structural stability under pressure.
- Gears & Shafts: Case-hardened, precision-ground alloy steel (16MnCr5 or equivalent) to minimize gear wear, reduce noise, and prevent pitting under heavy load.
- Journal Bearings / Bushings: High-performance bronze bushings or special composite heavy-duty plain bearings designed for low friction and extended lifespan under lubricated conditions.
- Sealing Elements: Premium FKM (Viton) dynamic lip seals or mechanical shaft seals for wide chemical compatibility, high temperatures, and leakage protection.
Packaging and Transport Protection
▔▔
- Industrial Packaging: Each pump is thoroughly drained, treated with anti-rust oil on internal and external surfaces, and sealed in heavy-duty polyethylene anti-moisture barrier bags.
- Moisture & Shock Protection: Packed in shock-absorbing custom molded foam or high-density foam inserts to prevent shock damage during transit.
- Fixation & Container Securing: Secured inside reinforced multi-layer wooden or plywood export cases (fumigation-free) with steel banding and internal anchor bolts.
- Bulk Cargo Shipping: Bulk orders are stacked on ISPM-15 compliant pallets, corner-protected, wrapped in stretch film, and strapped for full container load (FCL) or less-than-container load (LCL) transport.
Applications
▔▔- Heavy Gearbox & Turbine Lubrication: Provides forced oil circulation and continuous lubrication to gears and bearings in wind turbines, marine propulsion gearboxes, and steel rolling mills.
- Hydraulic Power Units (HPUs): Serves as the primary feed pump or circulation pump in industrial hydraulic systems to maintain system pressure and fluid cooling.
- Cooling & Filtration Loops: Acts as an offline kidney loop pump continuously driving oil through high-efficiency heat exchangers and fine particulate filter units.
- Bitumen, Resin & Viscous Media Handling: Applied in chemical processing plants to meter and transfer high-viscosity synthetic resins, paints, and polyols under thermal control.

FAQ
▔▔Q1: How do I select or confirm the correct Steimel Pump model code?
A1: Model codes indicate frame size, displacement per revolution, port direction, seal type, and pressure rating. Check your existing pump nameplate or provide your target flow rate (L/min), system operating pressure (bar), fluid viscosity (cSt), and motor RPM to our team for model matching.
Q2: What level of oil filtration is required for Steimel pumps?
A2: We recommend maintaining fluid cleanliness at ISO 4406 Class 19/17/14 or better. A suction line or inline filter with a rating of 25 to 50 microns is recommended to prevent solid debris from entering the pump gears.
Q3: How do I request a quote or check lead times for bulk procurement?
A3: Simply send us your required model code, quantity, and application requirements via email or WhatsApp. Our sales engineers will provide detailed specification sheets and competitive price quotations within 24 hours.
