Heavy-duty, low-maintenance Viking Universal Seal Pumps
Michael Smith Engineers is now supplying the Viking Universal Seal Pumps that are designed to meet the demands of heavy-duty, industrial pumping applications and incorporate essential features for reliable, low-maintenance pumping, even in challenging environments.
This range of internal gear pumps comprises 12 standard size options providing flow rates up to a maximum of 365m3/hr and pressures to 14bar. An important feature of Viking Universal Seal Pumps is that they are designed to accommodate virtually all types of seal; these can be packing, component or cartridge mechanical seals that can be easily fitted, usually without bracket modifications. This means operators have the flexibility to benefit from the latest sealing technology in order to maximise performance and meet the ever-changing fugitive emissions standards.
Viking Universal Seal Pumps are said to be easy to maintain, as the simple design of the internal gear pump means that there are only two moving parts. The back pullout design of the seal housing provides drive-end access to the pump seal for quick and easy replacement without removing the pump or rotor, thereby helping to keep downtime to a minimum. The seal housing is a solid one-piece cast bracket that helps to reduce shaft deflection and prolong seal life.
Improved bearings for longer life
The pumps are also equipped with heavy-duty bearings and bushings; the improved shaft support provided by these bearings helps to extend the life of the pump and the seal.
As well as accommodating virtually all types of seal, the Universal Seal pumps are available in a wide range of construction materials, including cast iron, ductile iron, cast steel, stainless steel and alloy C, allowing broad chemical compatibility with a wide variety of liquids. There are also jacketing options available for all the critical areas of the pumps, including the bracket, seal, casing, flanges, head and relief valve. This ensures that key components can be heated or cooled rapidly and accurately for faster start-up and uniform, accurate temperature control.
The pumps can handle a wide range of liquids with viscosities from 0.1 to 440,000cSt and are suitable for operation in applications with temperatures of -85 to + 425degC. They are suitable for high-volume, continuous-duty liquids transfer across many industry sectors including general processing, chemicals, food and beverage, oil and gas, refining, plastics, resins and rubber, and pulp and paper.
