The Vision Pump is a fish-friendly pump, especially designed to ensure the safe passage of fish. The Vision-CV can be used for drainage and irrigation applications, and it is available in a range of standard modulus with capacities ranging from 12 to 360m3/min.

Research showed that when fish bump into blades of regular pumps, they can get struck in cracks or injure themselves by its rough surfaces. By using a mixed-flow fan with just one fish-friendly blade, housed into a concrete shell in which the mouth is far away from the blades, we were able to create a fish-friendly pump

The Vision Pump is a fish-friendly pump, especially developed with fish safety in mind. The Vision-MC is a very fish-friendly pump, especially developed to allow fish to safely swim through it. The Vision-MC is suitable for both new and old pumping stations, and it is available in a range of standard modules, with capacities ranging from 12 to 360m3/min.
By applying a mixed-flow fan with just one fish-friendly blade, in addition to a metal housing and three fish-friendly rotor blades, we were able to design a fish-friendly pump.

Vision-MC Pump properties
✔️ Fish-friendly
✔️ High efficiency
✔️ High reliability
✔️ Compact design
✔️ Large unobstructed passage
✔️ Retrofitted to conventional propeller pumps

The Vision Pump is a fish-friendly pump, specifically developed with fish safety in mind. We designed the Vision-MV for smaller-scale applications, but still with fish safety in mind. This pump can be applied around playing fields, in small polders or in suburban areas.

The Vision-MV pump can be applied for the fish-friendly pumping of surface waters, with a capacity of 0.5 to 13m3/min at a discharge pressure of 0-5m.

In Netherlands, this pump type is mostly used in small polders or around playing fields. Other applications include, but are not limited to:
• Drainage of agricultural pastures
• Irrigation of pastures
• Regulation of water-levels in fishing ponds or nature reserves
• Pumping otherwise stagnant water
Vision-MV Properties
• Fish-friendly screw centrifugal fan
• Wide passage
• Minimal maintenance
• Clog-resistant
• Installable on sheet piles or in concrete wells
• Can easily be installed on bottom of tank/pond/etc
• Water-lubricated rubber lower bearing
• Long lifetime
• Directly coupled drive
• Vandalism-proof stainless steel cover
• Circular design
• Completely recyclable

The BVOP is a high-quality axial propeller pump with impressive performances, a high quality and a relatively low noise level. Bosman Watermanagement made use of its many years’ experience in the development of the BVOP pump for the discharge of water from and/ or management of the water level in polders and low-lying areas, and for supply of make-up water to canals with locks and in areas at higher altitudes in dry periods.

This pump with a range of seven standard modules, is available with capacities of 12 to 360 m3/minute with a delivery head of approximately 10 meters. The combination of a performed suction chamber with adjustable impeller blades and a spiral guide in a very generously-sized concrete volute achieves an ideal flow pattern with minimum losses and a large passage. Consequently, this design of this pump achieves a high efficiency. In addition, the pump requires only a shallow sub-mergence depth.

Three impeller configurations for each size of pump guarantee optimum performance without harmful cavitation or vibration zones.

The most suitable type of pump for specific application is determined using CAS (Computer Aided Selection). When selecting a pump type the specified duty point (flow/delivery head) needs to be realised. The minimum and maximum static delivery heads, the location of the optimum efficiency point, the NPSH etc. are additional factors that need to be taken into account when selecting a pump

Once a selection has been made, the CAS system will present the calculated pump curve and the desirable guarantee point.

Features & Benefits of the BVOP pump
• Low, fixed operating costs
• Extremely reliable pumping concept (no problems for many years)
• The pump’s special hydraulic design virtually precludes blockages
• No corrosion due to the concrete technology used for the pump
• No bend required, since the bend is integrated in the concept
• Removable inner components
• Standard driving components
• Low energy costs (high pump efficiency)
• Extremely low noise levels
• Easy to maintain
• The inner components can be removed from the pump for inspection without needing to drain the pumping station

In the Netherlands, the BCK pumps are mainly used for pumping sports field and small polders. BCK pumps are an economically attractive solution for water transport. The BCK is suitable for pumping surface water with a capacity of up to 11m3/min at a delivery head of up to approximately 3.5 meters.

Features & Benefits of the BCK pump
• Low maintenance design
• Almost insensitive to fouling, virtually precludes blockage
• Long service life virtually no maintenance
• Very low noise levels due to slow speed
• Installation in open water or in a (prefab) concrete pit
• Standard supply
• Float switch with float
• Thermal cut-out for overload protection
• Water-lubricated lower bearing
• Stainless steel protective cover
• Pump housing and standpipe made from hot-dipped galvanized steel

Based on years of experience in the design and construction of concrete snail shell pumps, Bosman Watermanagement has developed the Beveron: a mixed flow pump with impressive performance and a low noise level.

The Beveron is suitable for new constructions as well as renovations of pumping stations. The pump is available in a series of 29 standard modules covering a range of filtration speeds from 3 to 30m3/sec and heads between 1 and 10m. The Beveron achieves a high level of hydraulic efficiency due to perfectly matched components and its design ensures flow losses to be reduced to an absolute minimum. Moreover, Bosman Watermanagement has designed a unique suction box specifically for this pump that minimizes the required submersion depth.

The impeller is 3-bladed, half-open and cast from one piece which makes for a very durable product. The impeller is manufacturable out of various materials so that it can correspond with the specified requirements for strength and corrosion resistance

The volute has been specifically designed for the impeller and therefore has a very high hydraulic efficiency. The volute features a trapezoidal flow surface with a levelled floor. It is produced out of concrete and can be delivered as prefabricated elements on request.

The unique shape of the suction box has been designed specifically to reduce friction loss and the chance of the vortices forming down to a bare minimum. These vortices bring air with them into the pump and this impairs the effectiveness of the pump. The special design of the suction box is he result of extensive computer simulations. Trials in the test centre subsequent to the simulations have proven the high performance of this design.

Features and benefits of the Beveron pump
• Compact design
• High efficiency
• Use of long-life Residur® ceramic bearings
• Residur® ceramic bearings are maintenance free
• Low installation height
• Broad performance range
• Shaft seal and impeller are readily accessible
