Standard Sewage?

What Are You Pumping?

What Else Are You Pumping?

More Standard Sewage?

Frequent & Premature Equipment Failures

How does The Vaughan ‘Chopper’ Pump deal with all

of these problem areas that no-one else can handle?

Plugging at the suction intake.

Binding of materials around the impeller

Abrasives which rapidly wear standard materials

(Grit, Stones, Gravel)

Reweave of materials behind impeller

Shaft deflection and vibration when handling solids.

Approximately 22-24% of submersible pumps failures are associated with

Reweave of material behind the impeller & Shaft deflection.

Reweave of material behind the impeller & Shaft deflection.

Other Manufacturers ‘Non-Clog’ Type Pumps Can’t Handle This Heavy Duty Environment.

Plugging - A Familiar Sight?

A Blocked SewerSimilar to many sites throughout Northern Ireland, course hand rake screens had been installed at multiple SPS’s and were a constant drain on the NIW recourses. The objective was to remove the hand rake screens and thus remove the operational costs which typically consisted of:

• 1 operator - 5 days per week to manually rake the material into a bin.

• 1 lorry – at least 1 day per week to empty the bins.

This task will easily amount to an annual cost of over £3000 the addition

of any further costs arising from pump failures, repairs, sump tankering

etc which would be added to the base figure.

What would happen if the screens were removed? there would be premature failure to the existing standard Non-clog type pumps unless, they upgraded to the equipment designed for this duty, The Vaughan ‘Chopper’ Pumps

It is policy within many water authorities not to fit screens upfront to protect equipment. However, it is commonly accepted as a compromise over consistent and frequent failures of low cost and poor design of pumps.

The cost implications of this are substantial!!

Common Myth

All ‘Non-Clog’ or ‘Macerator’ or Cutter type

pumps are the same!

FALSE

Vaughan ‘Chopper’ Pumps are not to be confused with

other types or brands of chopper pumps, macerators,

grinder or cutter pumps.

The Vaughan Pump is a patented product and so it is

UNIQUE in the pump world.

Why is the Vaughan ‘Chopper’ Pump

Impeller design so efficient?

The Chopping action occurs as close to the most central part of the shaft rotation possible. This requires less energy even with the toughest materials.

Solids above 10mm

Solids below 10mm

Solids below 10mm are chopped in this new improved design with the new cutter nut tooth's leading edge scissor action design

Field adjustment with:

NO special tool or shims necessary!

The E-series design incorporates a unique back pull-out plate with external adjustments of all critical cutting clearances.

The ONLY pump available with ALL wear components in hardened materials

• All Wear Components – 61-64 Rockwell C (min 60)

• 4 times harder than standard grey iron.

• Designed to withstand impact.

• Designed to withstand abrasion.

• Minimal spares required over 20 years

A Comparison to Other Manufacturers?

Standard ‘Non-Clog’? Type Pumps

There can be no comparisons made between

Vaughan and other types of equipment.

All have Single Thrust on top

All have small shaft diameters Most commonly

All have Light Dutylower double Radial bearings

Other Manufacturers Lightweight Bearing Systems

NONE OF THESE DESIGNS WILL COPE WITH A HEAVY

SHOCK LOADING

All other Non-Clog? type pumps are basically a Centrifugal type with something added on: i.e.

Cutter Bar, Knife-edge, Grooves

NOT SUITABLE FOR HEAVY DUTIES

Other Manufacturers’ Mechanical Seals

LIGHT DUTY designs are no match for Vaughan

NO COMPARISON!NO COMPARISON!

SHAFT DEFLECTION

The main chopping action takes place between

the Auger-type impeller edge and the machined grooves on the I/D of the flange

Cutting Action takes place on the outer edge of impeller. This creates excessive radial forces to

the shaft causing deflection with resultant Mechanical Seal & Bearing failure.

How Confident Are We?

You will never see

anything like this from other Pump MANUFACTURERS!
