EXACTLY WHAT IS A MAGDRIVE PUMP SO WHEN / WHY WOULD I WANT ONE?
Mag-drive pumps really are a style of the magnetically-driven chemical-process pump which eliminate the requirement for shaft sealing. This greatly cuts down on the initial price of the pump in addition to day-to-day operational costs because there aren't any mechanical seals, seal-fluid containers, or cooling lines fitted.
The bond between your motor drive and also the pump drive is created using a magnetic connection which fits with the isolation shroud. Which means that there's no direct or indirect path by which any fluids or gases can escape which could pose a danger to both operators and also the atmosphere.
Mag-drive pumps come in a number of materials of construction including surefire/ductile iron, 316 stainless, and Hastelloy. This kind of pump plays a role in the technical standardization in process engineering because of its universal applications.
Mag-drive pumps can be found in close-coupled and lengthy-coupled (frame mounted) configurations.
When / why would I want one?:
Generally once the product being pumped is of the corrosive nature, or even the leakage of this product can harm operators or damage the atmosphere.
Types of such products could be:
Muriatic Acidity
Methane
Sodium Sulphate
Sodium Hydroxide
Sodium Hypochlorite
Sulphuric Acidity
What can be some typical applications individuals goods are utilized in?:
Tanker Unloading
Batch Chemical Processes
Specialty Chemicals
Column Reflux
Reactor Feed
So how exactly does it vary from, for instance, just one / double robotically-sealed pump?:
Most pump types, aside from magnetic drive pumps, possess a shaft which goes through the pump casing. The shaft is encircled with a seal which can leak. This leakage could be minimized first of all through seal quality, and next through a seal-fluid pressurization system ¨C generally known as “seal pots”. The adjacent image shows a disc pack Discflo lengthy-coupled pumping system, fitted having a seal-fluid pressurization system.
The seal-fluid pressure is greater compared to suction pressure within the pump. It prevents, or at best minimizes the opportunity of, the merchandise getting away beyond the seal.
For applications where the potential for the tiniest volume of product getting away might be hazardous, however, the mag-drive pump is really a solution as there's no shaft seal for that the merchandise to flee past.
This is often seen clearly within the graphic below, in which the product being pumped (proven in red) doesn't have a connection directly or not directed towards the pump shaft:

Benefits:
Reduced customer Existence Cycle Cost (LCC) by minimizing maintenance, operating & installation cost
An extensive selection of materials and accessories can be found to satisfy customer needs
Integrated options for connecting safety & monitoring devices, e.g. Goulds PumpSmart®
Design standardization & simplification to maintain easy maintenance & to reduce spares inventory needs
Drive magnet set up rich in-performance permanent magnets
Design Features:
Close-coupled Design
Arrangement eliminates have to perform pump/motor alignment. Single piece, dual-secure circle adapter accommodates needed motor sizes for optimum application versatility.
Lengthy-coupled (frame-mounted) Design
For easy dis-set up for preventative maintenance, overhaul or general periodic inspection.
One-piece Enclosed Impeller
Minimizes axial thrust for a longer thrust bearing existence. Unlike two-piece designs, one-piece construction eliminates the chance of front shroud failure.
Solid Stationary Shaft
The fully supported stationary design maximizes radial bearing existence and reduces shaft deflection. Straight geometry eliminates stress concentrations and chance of failure during pump operation
Rare-earth Magnets
High strength neodymium iron, provide high torque and difficult-start capacity without slip. A drive is synchronous.

In-line configuration:
An alternative choice provided with a mag-drive pump is definitely an in-line version, in which the pump is installed vertically. In-line mag-drive pumps are usually close-coupled, although a lengthy-coupled configuration can be done. The in-line configuration could be helpful where space is confined because the pump is installed directly within the line, as being a valve:
