Description

The VM, VMI, and VMN pumps are non-self-priming vertical multistage pumps of in-line design, flange, or with Victaulic coupling with equally sized suction and discharge ports. Stage construction with stainless steel impellers, chambers, and pressure casing. The pump stub shaft and the motor shaft of the IEC-standards motor are directly close coupled. All pumps are equipped with a cartridge-type mechanical seal for easy maintenance. VM, VMI, and VMN pumps have different pump sizes and various numbers of stages to provide the flow and pressure required.

Liquids to be pumped

The pump is designed for pumping freely flowing non-corrosive, non-explosive, and non-flammable liquids. The liquids to be pumped must also be free of solid matter, sands, fibers, and similar materials. Most common non-highly corrosive watery liquids, hot and cold liquids can be pumped with this pump. The suitability of factors, such as the pH level, contents of chemicals such as chlorides, oils, the temperature of the liquids, etc. Please contact Grampus if there are any questions as to whether certain liquids are suitable for pumping with the pump.
Mechanical Seals
Standard Cartridge type mechanical seal made of Silicon Carbide/Silicon Carbide/EPDM or Viton. Based on the type of application, alternative materials are available for the seal and the elastomers. The cartridge-type mechanical seal can be replaced in minutes without special tools and without dismantling the pump.
