ML Series Sliding Vane Pumps

Part of Blackmer’s Heavy Duty Line, the ML Series Sliding Vane Pumps are constructed with ductile iron and are ideal for handling everything—from thin non-lubricating solvents to highly viscous liquids or abrasive slurries. The highly customisable ML Series Pump is the ideal pump solution over a wide range of services: chemicals, petroleum, paint and coatings, pulp and paper, and food processing. Based on the materials being pumped, the ML Series pump can be configured with the right combination of bearing, seal and hub assembly, for a specific application. The removable hub allows for quick access to the bearing and sealing areas for routine inspection without removing the entire pump head.

Design Advantages

  • Modular bearing hub assemblies allow these pumps to be easily reconfigured in the field
  • Ductile-iron construction with bolt-on, internal relief valve

OUR RANGE OF BLACKMERML SERIES SLIDING VANE PUMPS

MLN SERIES

Ductile-Iron Pumps Ideal for Handling Thin to Highly Viscous Fluids

Model MLN Sliding Vane Pumps, part of Blackmer’s Heavy Duty Line, are ideal for handling thin to highly viscous fluids such as oils, asphalts, molasses and adhesives. These positive displacement rotary pumps are constructed with ductile iron and can handle everything—from thin non-lubricating solvents to highly viscous liquids or abrasive slurries. The MLN features internal self-lubricating carbon sleeve bearings and PTFE-impregnated shaft packing. Options include Blackmer® or commercial single or double mechanical seals.

Features

  • Symmetrical bearing support assures even loading and wear for long life
  • Optional commercial mechanical seals
  • External shaft stuffing box accommodates most standard aftermarket mechanical seal configurations
  • Available with internal sleeve bearings with external stuffing box

MLX SERIES

Ductile-Iron Pumps Designed for Handling all Types of Liquids

Model MLX Sliding Vane Pumps, part of Blackmer’s Heavy Duty Line, are designed for handling all types of liquids—from light non-lubricating to viscous abrasive slurries and waste oils. The MLX pump features internal mechanical seals with external ball bearings. The hub assembly in this model features external grease-lubricated spherical roller bearings and can be fitted with a wide selection of Blackmer mechanical seals. Options include hardened or wear-resistant internal components.

Features

  • Blackmer mechanical seal and ball bearing construction provide maximum reliability
  • Symmetrical bearing support assures even loading and wear for long life
  • External ball bearings are isolated from pumpage by mechanical seals to maximise bearing life and minimise contamination risk
  • Available with internal mechanical seals with external ball bearings

PRINCIPLE OF OPERATION

Blackmer sliding vane pumps use a rotor with sliding vanes to draw liquid into the pump. This rotor is located close to the wall of the cam so that a crescent-shaped cavity is formed on the opposite wall. Each rotor slot contains a sliding vane. As the rotor rotates, centrifugal force, hydraulic pressure, and push rods work together to extend each vane to the casing wall. This creates an expanding cavity on the inlet side – creating a vacuum that pulls liquid into the pump. The liquid is trapped between the vanes and the casing wall. The rotor rotation moves the liquid cavities around to the outlet side of the pump. The vanes are forced back into their slots at the outlet side, decreasing the cavity size and forcing the liquid through the outlet port.
