SPECK standard block 25/160

Product information "Standard block 25/160"

The block design enables high circulation rates with little space requirement. The motor can be replaced without having to completely disassemble the pump or remove the mechanical seal. The highly wear-resistant bellows mechanical seal is independent of the direction of rotation and maintenance-free. This is also lubricated by the medium via an internal circulation line and enables a long service life. The pump shaft made of stainless steel 1.4571 is additionally protected by a shaft protection sleeve also made of stainless steel 1.4571. This prevents wear on the pump shaft. Directly mounted, low-noise, surface-cooled, replaceable DIN IEC three-phase standard motor in German brand quality. Energy efficiency class IE3 from 0.55 KW, including PTC sensor with fixed bearing on the pump side. The motors are manufactured ex works with sealed condensation drain holes.

Area of ​​application

Swimming pool water circulation and filter flushing as well as operation of swimming pool attractions in public swimming pools. Can also be used in irrigation, drainage, water supply, shipbuilding and industry.

Execution

Non-self-priming, single-stage volute casing pumps with performance allocation and main dimensions according to NF E 11-112 and DIN EN 733 (replacement for DIN 24255). Pump and interchangeable standard motor are flanged to form a block unit. The volute casings are fitted with replaceable, corrosion-resistant wear rings. The closed, balanced impellers can be individually adjusted to the respective operating conditions. The balancing is carried out in quality class 6.3 according to DIN ISO 1940. This ensures optimal smooth running and longevity of the entire pump.
