The pumping set is equipped with a high efficient pressure pump unit. Thanks to its robust construction, it is ideal for pumping river water containing solid particles. The pump can be provided either with soft packing or a mechanical seal for trouble-free operation. It is therefore very reliable and easy to maintain.
The impeller blade is formed by helical surface which rises along the conical shell. Different versions of blade geometry and helical surfaces allow SPIRAM pumps to function in a wide range of high-speed hydrodynamic machines. An impeller of this type makes it possible to achieve speed rates similar to diagonal pumps.
Thanks to the single-blade design, the pump impeller has large flow passage, which you will appreciate either when handling sludge or liquids with a high content of solids.
HIGH EFFICIENCY – MINIMUM OPERATING COSTS
The SPIRAM pump has extremely high efficiency (above 91%) while maintaining maximum passage of solids (up to 300 mm). These key features minimize the likelihood of the pump clogging, so ensuring reliable operation of the unit at minimum operating costs.
All components of the pump unit are made of highly resistant alloys and precious metals. Moreover, the production of these components from die-casting through machining operations up to the assembly of the unit is carried out in Slovakia. This method of quality control "under one roof" guarantees the achievement of the highest accuracy necessary for long-term operation.
ADVANTAGES OF USING A SPIRAM PUMP
Priming of the pump is facilitated by a vacuum system consisting of a diaphragm vacuum pump driven by a belt transmission, a set of vacuum hoses and a priming member, which automatically terminates the process of evacuation of the pipeline once the working volume is primed. Alternatively, a nozzle can be used.
The power unit is a 4-stroke supercharged diesel engine including accessories (Power-Pack) with an output of 15 - 560 kW at 1450 RPM. The engine complies with the Stage V emission standard according to the Regulation 2016/1628 of the European Parliament. Engines that have been on sale since 2019 with outputs from 19 to 560 kW and meeting lower standards must not be used to drive mobile pumps, non-road construction and agricultural machineries. The motor is equipped with a control panel and a 12V electric starter. The fuel tank is located either in the base frame or it is a separate tank of sufficient volume to ensure continuous operation of the unit for a period of at least 12 hours. The motor is firmly connected to the pump by means of a special bearing bracket and a high-quality flexible coupling which transmits no vibrations.
A base frame made of solid iron profiles which are either hot-dip galvanized or surface treated with durable polyurethane paints is used as the load-bearing structure. The entire structure is fixed to an approved trailer. The trailer surface is hot-dip galvanized to prevent corrosion and prolong its lifetime.
Both the suction and the discharge lines of the pump unit can have a pipe fitting that reduces the nominal bore from a bigger inner diameter to a smaller inner diameter in order to simplify work under difficult conditions. Pipe sizes and lengths are adapted for operators to work in compliance with legislation applicable in Slovakia (e.g. weight considerations). Unified quick couplings are used to connect pipes.
Pump unit can be mounted with its frame on an approved trailer. The trailer complies with all road traffic regulations. The trailer is equipped with a height-adjustable tow bar, which allows it to be easily and quickly connected to different vehicles.
Pump unit can be equipped with the housing - a rigid structure to cover the engine, including engine sound proofing to meet the required standards.
