MLN4B Sliding Vane Pumps

The MLN4B Sliding Vane Pump is a heavy-duty ductile iron rotary pump designed for the transfer of fluids with a wide range of viscosities. It is part of the MLN4B series of sliding vane pumps, engineered for durability and efficiency in demanding industrial applications. The pump features a cast ductile iron body, ensuring high structural strength and resistance to wear, making it suitable for continuous operation under challenging conditions.

The MLN4B sliding vane pump is designed with internal self-lubricating carbon sleeve bearings, which reduce maintenance requirements and improve operational reliability. It also utilizes PTFE-impregnated shaft packing to ensure a tight seal and reduce fluid leakage. The pump can handle a variety of fluids, including thin non-lubricating solvents, as well as highly viscous substances such as oils, asphalt, molasses, and adhesives. This versatility makes it ideal for industries such as chemical processing, asphalt production, food, and manufacturing.

Dimensions and operational specifications of the MLN4B sliding vane pump typically include a flow rate range of up to 40 liters per minute (approximately 10.6 gallons per minute), with a maximum pressure capability of 10 bar (145 psi). It has a size that accommodates standard flange connections (often 2-inch or 3-inch port sizes) and features a compact, robust design suitable for installation in various orientations.

• Flow rate: up to 40 L/min (10.6 GPM)
• Maximum operating pressure: 10 bar (145 psi)
• Construction material: ductile iron
• Sealing options: Blackmer® or commercial single/double mechanical seals
• Bearings: internal self-lubricating carbon sleeve bearings
• Impeller: sliding vane design with precision-machined components
• Operating temperature range: typically -10°C to +80°C (14°F to 176°F)

This MLN4B sliding vane pump is suitable for applications requiring reliable, low-pulsation fluid transfer, especially where viscosity varies significantly. It is a cost-effective solution for handling viscous or abrasive fluids in industrial processing, manufacturing, and maintenance operations. Designed for durability and ease of maintenance, the pump is ideal for scenarios requiring robust performance within a moderate budget, ensuring long service life and operational efficiency.

Included in the package are the pump assembly, intake and discharge flanges, and a set of mechanical seals. Not included are hoses, motors, or secondary mounting hardware, which are typically purchased separately. The MLN4B sliding vane pump requires regular maintenance, including periodic seal inspection and bearing lubrication, to ensure optimal performance. It can be cleaned with standard industrial cleaning agents, and its mechanical seals are warranted for a specified period according to the manufacturer’s guidelines.
