ML Series Sliding Vane Pumps

The ML Series Sliding Vane Pumps are positive displacement rotary pumps designed for reliable and efficient fluid transfer in demanding industrial environments. Manufactured with a durable ductile iron housing, these pumps are suitable for handling a wide range of substances, including thin non-lubricating solvents, highly viscous liquids, and abrasive slurries. Their robust construction ensures long service life and consistent performance under variable operating conditions.

Materials: The main body and internal components are constructed from ductile iron, with options for stainless steel or other corrosion-resistant materials for specific applications. Seals are typically gland or mechanical, selected based on chemical compatibility and pressure requirements. The pump features a precision-machined rotor and a sliding vane assembly made from wear-resistant polymers or metals.

Dimensions: The ML Series pumps are available in multiple sizes, with flow rates ranging from 5 to 150 liters per minute (1.3 to 39.6 GPM). The typical inlet/outlet connection sizes are 1 inch NPT or ISO threaded, compatible with standard piping systems. Pump height varies between models, generally between 250 mm and 400 mm, and weights range from approximately 3 kg to 15 kg depending on configuration.

Features:

• Flow rates from 5 to 150 liters per minute (1.3 to 39.6 GPM).
• Operating pressure capacity up to 10 bar (145 psi), depending on model and configuration.
• Removable hub design allows for quick access to internal bearings and seals for maintenance or inspection.
• Customizable configurations include bearing types, seal options, and hub assemblies tailored to specific application requirements.
• Constructed with ductile iron housing and corrosion-resistant materials for enhanced durability and longevity.
• Can handle fluids with viscosities ranging from 1 to 10,000 centistokes (cSt), facilitating use across diverse industries.
• Compatible with standard industrial piping and mounting arrangements.

Use Cases: The ML Series Sliding Vane Pumps are ideal for applications in chemical processing, petroleum refining, paint and coatings manufacturing, pulp and paper production, and food processing. They are especially suited for situations where reliable, customizable, and budget-conscious pumping is required, such as transferring aggressive chemicals or viscous fluids.

Designed to provide consistent performance with minimal maintenance, these pumps are suitable for shop floors, processing plants, and portable setups. Their straightforward design makes them accessible for routine inspections and repairs, making them an economical choice for budget-conscious operations without sacrificing performance standards.

Included: Each pump ships with the assembled pump head, rotor, and standard sealing options. Optional components such as custom seals, bearings, and inlet/outlet adapters are available. Not included are piping accessories, mounting hardware, or electrical connections.

Care Instructions: Regular inspection and lubrication of bearings are recommended. Seals should be checked periodically for wear and replaced as needed. The pumps can be cleaned with compatible solvents and mild detergents. A factory warranty covers manufacturing defects, and routine maintenance is advised to ensure optimal performance over the lifespan of the ML Series Sliding Vane Pumps.
