SPX HOSE PUMPSImprove your process performance

The pumping action results from alternately compressing

and relaxing a machined hose element between the

pump housing and the compressing shoes. The fluid

ahead of the shoe is pushed towards the discharge while

the rebounding hose behind the shoe draws more fluid

in. With 100% compression at all times, the pump does

not slip, providing unbeatable metering accuracy and

pressure performance. With no pump seals, seats or

valves, abrasive slurries are no problem. With the fluid

contacting only the inner wall of the hose, the pump is

perfect for aggressive products.

Engineered simplicity

Good News . . . a pump with no seals or valves

dependability of the SPX which:

Doesnt require expensive ancillary equipment. No check valves, sealing water flush systems, or rundry protection. Its simple to own and operate

Pumps abrasive slurries, corrosive acids, gaseousliquids, as easily as water - no vapour locking

Is ideal for high viscosity or shear sensitive product

Can run dry indefinitely without damage

Has one wetted component - the hose element. No seals, ball-checks, diaphragms, glands, immersedrotors, stators or pistons to leak, clog, corrode andreplace

Is fully reversible to blow out clogged suction anddrain lines safely

Has a suction lift capability up to 9.5 metres and is self-priming

Does not slip, giving true positive displacement foraccurate and repeatable metering

Downtime is moneySave both with the SPX by reducing your maintenance.

To completely rebuild an SPX all you need is a spanner, a

hose, and a few minutes. Drain the lubricant, unbolt the

flanges, replace the old hose and youre back up and

running. No complex parts lists, no special tools, and no

need to bring the pump to a maintenance shop.

SPX - The apex of pump evolutionWith over 50 years experience, Watson-Marlow Bredel

leads the way in hose pump technology, engineering

the new standard for hose pumping with its unique

SPX direct-coupled design. The SPX combines the

small footprint of close-coupled pumps with the reliability

and ease of maintenance of long-coupled designs.

While close-coupled pumps are extremely compact, this

out-of-date technology still used by other hose pump

manufacturers relies on the gearbox to seal the pump

housing and support the heavy overhung load of the

pump rotor. While close-coupled pump competitors offer

optional long-coupled pumps to improve gearbox and

bearing life, this comes at the cost of substantially

increased footprint and the added complexity of coupling

alignment and maintenance.

The SPX direct-coupled design contains heavy duty rotor

bearings within the pump rotor, eliminating any overhung

load. Ultra compact SPX high-torque gear drives then

align directly to the pump housing and is fully protected

by an innovative buffer zone. No other pump achieves the

reliability, simplicity, and compactness of the SPX hose

pump.

The essential component of high-performance hose

pumps is a hose that is constructed of layers of

rubber reinforced by winding several layers of nylon

cord. The inner layers are extruded. The inner layer is

available in a range of rubber compounds. After the

hose is constructed, it is then machined. Machining is

the final step in hose manufacture and is critical to

ensure that exact tolerances are held.

Hose construction

The hose is the key

The machined hose element is the single most vital

component for the performance, durability, and efficiency

of the hose pump. To ensure perfect compression and

consistent, reliable performance, Watson-Marlow Bredel

manufactures hose elements from high quality

compounded rubbers, reinforced with four individual

layers of braided nylon and finished by high precision

machining. Perfect compression eliminates slip which, in

other pumps, can destroy shear sensitive product, reduce

metering accuracy, or allow abrasive slurries to wreak

havoc on wetted parts. Watson-Marlow Bredel engineers

hose elements to meet the flow, pressure and temperature

characteristics of your toughest applications.

We are the only hose pump manufacturer to

machine our own hose elements. No other

competitors take this degree of care.

Low cost sludge pumping at Greenfield STW

A Watson-Marlow Bredel SPX80 hose pump installed at GreenfieldSewage Treatment Works handles 19,000 litres/day in a primary tankdesludging operation.The SPX80 is fitted with a 3kW fixed speed drive and is pumping 5%sewage sludge from the tanks. Suction is through five metres of 100mmdiameter pipe and a further fifteen metres of 150mm diameter pipe with aslight lift. Discharge is to a thickener through 100 metres of 100mmdiameter pipe with a 5 metre vertical rise.With the sludge contained within the hose throughout pumping, and noglands, valves, rotors or pistons to wear or leak, this provides an optimumcombination of abrasive resistance, mechanical strength and resilience.All this adds up to long hose life and minimal pump maintenance,therefore low whole life cost.Solids handling

Acids, alkalies and plastic sacks, no problem to an SPX50

Where a variety of other pump types had been tried and had failed, anSPX50 hose pump triumphed in a difficult effluent pumping duty at a bulkchemical supply company.

The effluent can be acidic or alkaline with up to 10% solid content, oftenconsisting of sodium bisulphate, caustic potash, hydrochloric and sulphuricacids in varying concentrations. These aggressive chemicals, together withabrasives such as calcium deposits, grit and sludge, as well as wire, plasticssacks, tie wraps, labels and bottle tops, create a seemingly impossiblemixture for a pump to handle.

Effluent and surface run-off from the entire site drains into a centrally located,six metre deep collection sump. Operating automatically under the control ofhigh and low level float switches, the SPX50 pumps from the sump against ahead of approximately three metres, to the treatment plant.

Putting quarry waste to good use with an SPX100

Bardon Aggregates Industries Plc has over 70 aggregate operations locatedacross the UK for crushing rock, sand and gravel. One of these sites washaving to cope with a large build-up of dust fractions; the result of years ofrock processing. They had to seriously consider how they could take theleftover and worthless dust and transform it into concrete sand.

The redundant fractions are mixed with water and placed in a settlementtank to create a thick dense sludge for disposal. Such an abrasive materialneeded a pump that would be rugged enough to withstand the quarryingenvironment.

The SPX100 chosen for the application pumps the dense sludge from thesettlement tank, 70 metres into the ground and vertically up a 15 metre cliffto a lagoon. Waste levels at the plant are now under control and thecompany is benefiting from the waste left over.Abrasive slurries

Fifty different recipes for SPX50 success

In the manufacture of high quality salad dressings and mayonnaise, an SPX50

pumps' ability to handle a wide variety of viscosities up to 30,000 cP,

particulates including mustard seeds, whole mini capers, kibbled onion,

chopped olives, rosemary, chopped horseradish and diced bell peppers, in

varying concentrations, won the order over air operated diaphragms pumps.

As well as the pumps ability to cope with both high and low viscosity

products without fall off in performance, of equal importance are easy

cleaning and a smooth, low-shear, low turbulence pumping action, which

obviates risk of the product thinning or damage to particulate ingredients in

the dressings.

Safe nuclear sludge re-processing

A key part of treatment of intermediate level radioactive waste (ILW) is bycement encapsulation. This involves retrieving homogenised sludge fromexisting tanks, pumping sludge through a cross flow filter system todewater it, and then discharging batches of conditioned sludge to thedrums. By mixing the sludge with cement and packing it in drums, it canbe physically encapsulated for storage and transportation. The heart ofthis bottling process is dependent on SPX hose pumps, including twoSPX65 models and another two SPX80 models.

Having a high suction lift was an important criteria for the pump selectedfor this application but an even greater consideration was their non-contacting pumping process.Safe containment
