Side channel pump PN 0 self-priming, according to DIN EN 7 SRZ Technical description
SRZ pumps are self-priming side channel pumps in multistage construction capable of handling aerated liquids. They have been developed especially for heavy duties in all industrial areas. Clean, slightly contaminated or aggressive liquids can be handled without problems under the most difficult operating conditions. The most important characteristics of these pumps are: self-priming capable of handling aerated liquids low noise level easy to maintain applicable for temperatures up to 220 C possibility of constructive variants The SRZ pump is very reliable and easy to maintain. Latter is of great importance for those application fields where high security and constant readiness for service is indispensable. You have for example the possibility to change shaft seals, antifriction-bearings, etc. without removing the pump of the piping system. Technical data: Capacity: 0, - 5 m /h Head: 5-50 m Speed: 10 (1750) 1/min. Temperature: 0 C to + 220 C (660 series: up to + 1 C) Working pressure: 0 bar Viscosity: max. 20 cst Suction head: max. 7.0 m Proportion of gas: max. 50 % Drive: three-phase motor 0,55-55 kw Characteristics of construction horizontal self-priming side channel pump in heavy execution PN 0 modular construction pressure relieved vane impellers (ill. 1) suction and delivery branches are radially directed upwards sleeve bearing lubricated by the liquid pumped two grease-lubricated exterior antifriction-bearings in removable bearing-supports (ill.2) direction of rotation: clockwise seen from driven shaft end Flange according to DIN 2501, PN 0 shaft seal: standard mechanical seal possibility of cooling or heating Pumps for temperatures higher than 120 C (K-execution): For the selection of pumps resp. of their execution you can proceed according to illustration no. in consideration of the chemical resistance. On principle pumps in K-execution have the following constructive modifications: increased clearance between impeller and stage high temperature bearing heat-resistant paint cooling connections at the foot (1-2 l/min, max. 10 bar) compensation of thermal expansion Important: Pump types of this series consist of standard components. They show an uniform perfomance level and are standardized according to DIN EN 7 and therefore interchangeable with types of other German producers. Application: SRZ pumps are generally used in many areas, for example: chemical industry installation and apparatus engineering process engineering refrigerating installations boiler feed installations The great number of material- and shaft seal variants guarantees a large application field. Special casings for shaft seal permit the mounting of any mechanical seal. These advantages put the big enterprises into position to keep their particular company standard. A special execution (K) for handling boiler feed water at a temperature higher than 120 C exists. This execution is applicable up to 220 C. Please note: casing pressure = positive suction pressure (steam pressure) + head at the minimum flow rate.

Performance curve The technical documentation includes detailed curves. Attention: The limit on the left side of the curve represents Q min. The capacity has not to be continually inferior to this value. Otherwise pump could be damaged. For start-up and during the operation the suction and the discharge valve must always be open. In case of capacity fluctuations we advise to use a by-pass. 6
