UNIVERS-P Herborner Pumps
The process pumps of the UNIVERS-P series were constructed especially for hard use in pumping stations and sewage treat-ment plants with direct operation via coupling or V-belt drive. Reliability and long operating periods together with the highest possible efficiency are priorities during development – these fac-tors all combine to achieve very low life cycle costs. The higher flywheel mass inertia made possible in the design minimises the impact of water hammer in the pipeline system.

The UNIVERS-P is ideally used in process-technology plants and municipal businesses. It is especially suited for delivery of uncleaned sewage, dirty water, faeces, sewage sludge, moor mud, pool water, and paper, cellulose, and wood suspensions. With the highest degree of operational safety even in areas where there is an explosion hazard, close coupled sewage pumps contribute to the fault-free functioning of sewage trans-port systems, pump stations, sewage treatment plants, public facilities, factories, vegetable washing facilities, slaughterhouses, indoor, outdoor, and adventure swimming baths, water parks, paper and sugar factories, breweries, preservative industries, department stores, schools, and residential buildings.
UNIVERS-P Herborner Pumps
The process pump UNIVERS-P guarantees operational safety and productivity during continuous operation.
The single-stage centrifugal pumps of the UNIVERS-P construction series provide optimum adaptation to system conditions and spatial circumstances. This is made possible by the various combinations achievable due to the modular construction. The pump casing forms the basis. It accommodates the various impeller forms and drives. The drive unit is an integral part of the pump.
Motor
Premium efficiency class three-phase motor (IE3). Frequency regulation of pumps is possible and depends upon the working conditions: from 30 to 50 Hz and from 30 to 60 Hz.
Shaft sealing
The shaft sealing on the pump side is effected in all models via a maintenance-free mechanical seal, which is independent of the direction of rotation and made from wear-resistant silicon carbide (SiC). Long-fibre materials are crushed by the rear cutting ring of the impeller beforehand.
A mechanical seal made of carbon/chromium molybdenum cast seals the drive side.
Noise
Noise emission is determined by complex influencing factors such as size, materials, operating and installation conditions. As early as the development stage, hydraulic measures and solid construction are used to reduce noise emission. The maximum sound pressure level is generally determined by air, magnetic and bearing noise from the drive motors. Noise levels are below the permissible limit curves specified for electrical motors as defined by DIN EN 60034-9. Lowest noise emission during operation close to Q optimal (greatest efficiency).
In addition to the process pump UNIVERS-P, we also offer pumps for specific use with difficult pumped media which are attuned to the desired requirements.
