Aquastream Mixed Flow Pumps - Product Brochure

Aquastream – Mixed Flow PumpsTypical Applications:• Circulating duties• Water boosting • Irrigation • Fish farms • Many other general service applications for both cleanand slightly contaminated non-corrosive liquidsSPP PUMPSThe success of the high efficiency mixed flow pump is based on its ability to produce large flow rates at low to mediumheads. The specially developed hydraulic design produces efficiency up to 89% depending on the size. For outrightperformance and reduced running costs, the Aquastream is clearly in a class of its own.This range is used in a wide range of industrial and environmental applications and can be used on either clean or turbidwater. The mixed flow impellers are cut to each duty point to minimise the motor power used.The flexibility does not stop there as these units can be supplied in horizontal, vertical open shaft or vertical direct mountedarrangement. Also, the Aquastream pump can be coupled to either an electric motor or diesel engine drives.Materials of ConstructionCasing Cast ironImpeller Cast iron/bronze/stainless steelShaft High tensile steel/stainless steelShaft Sleeve Stainless steelLantern Ring BronzeSealing Options Soft packed or mechanical sealSpecificationsPumps Models: 12Discharge Range Sizes: 200mm to 650mmTemperature: 90ºC maximum-10ºC minimumMaximum Capacity: 1,350l/sSpeed: Up to 1,450 rpm (depending on pump size)Maximum Differential Head: 28mElectricity Supply: 50 and 60 HzOperating Pressure: 3.6 bar maximumSealing Options: Soft-packed or mechanical sealDesign Features1 Rugged cast iron volute with integral cast feet to withstand toughoperating conditions2 Proven, self-lubricating system with gland flushing pumped byliquid piped from the discharge branch3 Substantial shaft/bearing arrangement with shaft carried in robust,oil-lubricated thrust and journal ball bearings4 Cast iron bearing housing, incorporating oil reservoir, is secureddirect to pump casing5 For proper shaft protection, sealing is by soft packed gland withreplaceable stainless steel shaft sleeve6 The specially designed mixed flow impeller will handle solidparticles up to 70mm, depending on pump modelTechnical Design BenefitsAquastream can be put to work efficiently in a wide range of industrial and environmental applications.It can be used for clean or turbid water (for which it is particularlysuited) and is therefore an excellent choice for irrigation and drainageschemes when coupled to a low speed motor or diesel engine.An important feature is the semi-open impeller design for efficient handling of liquids containing solid particles.234156Wide Range of Sizes• An excellent range of pump sizes are available – all offered withpriming arrangements varying from simple manual to fully automatic• The pumps can be supplied for both horizontal and vertical mode• When used vertically, this can be either open shaft or direct coupledto the motor of your choicewww.spppumps.comSPP039-OCT07 SPP reserve the right to continually develop and improve products.
