ump group (RD-LFM) All pumps are designed for right-hand rotationunless left-hand rotation is explicitly stated in theorder (direction of rotation when looking at thepump shaft). With left-hand rotation, suction andpressure sides are the other way round! Thepumps are provided with plate stating the direc- tion of rotation. The pump is supplied with an FKM (Viton) radial shaft seal and pressure relief valve set to anopening pressure of 8 bar and sealed. The pump group is supplied with bell housing, coupling,base, and motor. The nominal power rating on the pump shaft as well as the delivery rate refer to = 1 1/min, 5 bar pressure and an oil viscosity of 5 cSt.The 5 cSt correspond approximately tothe limit temperatures acc. to works standardW 5, table 2. Deviation of oil delivery rate 5%. Design of three-phase motors Motors manufactured by Loher are preferred. They are supplied in mounting type B5, type ofprotection IP5 and insulation class . Supplyvoltage and frequency should be stated in theorder. Attention! These motor data do not refer to type OLOO (data on request only).Version du groupe de pompage RD-LFM Toutes les pompes ont conues pour tourner droite, sauf si la rotation gauche express- ment spcifie passation de la commande com-merciale (le sens de rotation sentend en regar-dant sur larbre de pompe). En rotation gauche, le ct daspiration devient celui de refoulementet inversement. Sur les pompes est appose laplaquette directionnelle correspondante. La pompe est livre avec une bague radiale - vres et ressort en FKM (viton), une vanne limita-trice de pression rgle pour souvrir une pres-sion de 8 bars et plombe. Le groupe est livr ac- compagn du lanterneau, de laccouplement, dupied et du moteur.La puissance nominale au niveau de larbre depompe et le dbit de refoulement de lhuile sen- tendent moteur tournant = 1 1/min, huile 5 bars et dune viscosit de 5 cSt. Les 5cSt correspondent approximativement aux tem-pratures limites fixes au tableau 2 de l
