SP-LR-line
Self-priming liquid ring pumps for hygienic process applicati***, according to EHEDG
Materials
All parts that come into contact with the pumped liquid are made of stainless steel, Materials nr. 1.4404. At request these parts can also be made of Materials nr. 1.4435 or Materials nr. 2.4602 (Hastelloy C22).
Drives
The SP-LR pumps are mounted with a close coupled stainless steel encased IEC B3/B5 foot/flanged motor and fitted with adjustable feet. The motor and impeller are coupled by a balanced stainless steel stub shaft.
The motor can be supplied in all efficiency, isolation, protection and voltage classes. Also ***ailable in ATEX compliant version and in noise reduced execution.
The SP-LR pumps can be supplied in a bearing house
execution.
Self Priming Liquid Ring Pumps
The self priming liquid ring pumps SP-LR are special designed for pumping liquid that contains air or gas. This type of liquids are CIP return applicati*** in the food-, dairy-, beverage- and pharmaceutical industry
Ultra clean
All liquid contact parts of the SP-LR pumps are compliant with the relevant standa***.
The open impeller ensures an optimal cleaning of the shaft and seal chamber. The impeller is dry mounted.
The applied “O”-ring c***tructi*** are designed to minimize the liquid contact and at the same time to provide an optimal cleaning of the contact faces
Shaft sealing systems
According to the hygienic standa*** of EHEDG the pumps can be supplied with several types of shaft sealing.
The standard shaft sealing is a single internal mechanical seal, however a single internal mechanical seal with quench is ***ailable as option.
The mechanical seals are ***ailable in the following materials combinati***:
· carbon to CrMo-steel
· carbon to silicon carbide
· carbon to ceramic
· silicon carbide to silicon carbide
· tungsten carbide to tungsten carbide
The mechanical seals are ***ailable with EPDM, Viton, NBR and Teflon “O”-rings.
All materials comply with FDA - CFR 21 or the equivalent european standa***.
Besides the SP-LR-line pump assortment in this brochure the Pomac delivery program comprises an extensive choice of hygienic pumps. More detailed information on these pump types is ***ailable and will be sent to you on request.
SP-LR-线
根据 EHEDG 的说法，用于卫生过程应用的自吸式液环泵
材料
所有与泵送液体接触的部件均由不锈钢制成，材料编号。 1.4404。根据要求，这些部件也可以由材料制成。 1.4435 或材料编号。 2.4602（哈氏合金 C22）。
驱动器
SP-LR 泵安装有紧密耦合的不锈钢封装 IEC B3/B5 支脚/法兰电机，并配有可调节支脚。电机和叶轮通过平衡的不锈钢短轴耦合。
电机可提供所有效率、隔离、保护和电压等级。还提供符合 ATEX 标准的版本和降噪执行版本。
SP-LR 泵可以在轴承箱中提供
执行。
自吸液环泵
自吸式液环泵 SP-LR 专为泵送含有空气或气体的液体而设计。这种类型的液体是食品、乳制品、饮料和制药行业的 CIP 回流应用
超洁净
SP-LR 泵的所有液体接触部件均符合相关标准。
开放式叶轮确保对轴和密封腔进行***佳清洁。叶轮是干式安装的。
应用的“O”形环结构旨在***大限度地减少液体接触，同时提供接触面的***佳清洁
轴密封系统
根据 EHEDG 的卫生标准，泵可以配备多种类型的轴封。
标准轴封是单一内部机械密封，但也可提供带淬火的单一内部机械密封。
机械密封有以下材料组合可供选择：
·碳对铬钼钢
·碳到碳化硅
· 碳到陶瓷
·碳化硅转碳化硅
·碳化钨转碳化钨
机械密封可提供 EPDM、Viton、NBR 和 Teflon “O”形圈。
所有材料均符合 FDA - CFR 21 或等效的欧洲标准。
除了本手册中的 SP-LR-line 泵系列外，Pomac 交付计划还包括广泛的卫生泵选择。可提供有关这些泵类型的更多详细信息，并将根据要求发送给您。
