Series ESISO 2858 (ISO 5199) End SuctionBare Shaft Industrial Centrifugal

Pumps 50Hz

ES Series - Bare Shaft PumpsThe ES SERIES of pumps complies fully to the international standard ISO 2858 and ISO 5199.

DESIGN FEATURESThis pump includes the back pull-out design, and when a suitable spacer coupling is fitted to a direct coupled unit, the casing and motor can remain in position while all other pumpparts can be removed for simple and quick maintenance.

The volute casing is fitted with a replaceable wear ring and has asuction vane to give smooth flow into the double shroudedhydraulically balanced impeller.

Only four shaft assemblies are required to cover the total rangeand this gives many common interchangeable parts for pumpsfitted to the same shaft.

The standard pump is fitted with a mechanical seal chamber. Allthese pumps can be fitted with a packed stuffing box incorporating a lantern ring.

Pumps can be supplied as a bare shaft unit, or in many otherarrangements, including complete with coupling, guard, baseplate and either electric motor or engine.

Maximum TemperatureWith standard packed gland - minus 10oC to 140oC.

Maximum PressureMaximum operating pressure 1600kPa.Maximum test pressure 2100kPa.

Maximum SpeedMaximum direct coupled speed for pumps varies between 3600 RPM and 1500 RPM depending upon pump size andmethod of drive.

MATERIAL OPTIONS Closest Australian Equivalents

Bronze wear rings - fitted as standard, replaceable front and rear wear

rings with optional materials, for a trouble free lifecycle.

Bronze impeller - in a closed design is fitted as standard to prevent

corrosion in stationary or inactive situations. Cast 304SS or 316SS are

available on request. The use of 3-D solid model Computer Aided

Design (CAD) and Computational Fluid Dynamics (CFD) ensures high

efficiencies, reducing overall running costs. Impeller diameters can be

trimmed to suit specified performance.

Pump casing - high efficiency Cast Iron volute castings, with flanges

rated to PN1.6MPa (16bar), drilled to AS2129, Table E. Material

options: 304SS or 316SS.

Casing oring - re-usable orings in Nitrile for ease of re-assembly

(optional materials available).

Back pull-out design - allowing for easy removal of rotating element

without disturbing the pipe work, lagging, motor or pump volute casing.

This is proven to reduce downtime whilst performing routing

maintenance.

Enlarged Shaft - reduces shaft deflection. Standard in 420SS and

316SS as an option. Tapered and keyed shaft design allowing ease of

removal in maintenance and positive locking whilst in operation.

Shaft seal - single, high quality Aquaplus or approved equivalent

mechanical seal with carbon vs ceramic fitted as standard with other

options such as silicone vs silicone or high temp also available.

Tappings - convenient suction and discharge pressure gauge tappings

plus volute drain, fitted as standard to all Aquaplus ES series pumps.

Bearings - Heavy duty SKF or approved equivalent, greased for life,

reducing maintenance. Housed within removable bearing cap cover

assembly, protected by a quality manufactured lip seal reducing

ingress of moisture or foreign matter.

Bearing housing - Robust / heavy duty, manufactured in high

strength cast iron providing trouble free life cycle.
