Explosion-proof centrifugal electric pump -25 EX is designed to pump out polluted ground and industrial wastewater with a temperature of up to 35 ° C with pH = 5-10, a density of up to 1100 kg/m, containing mechanical impurities up to 10 % and maximum size up to 5 mm, as well as impurities raw oil up to 10 % by weight, which can contain up to 3 % sulfur in a non -free state and paraffin up to 7 %. The use of an electric pump is allowed for pumping in emergency medium modes containing up to 100% raw oil.
Long stay, including work, In such environments, no more than 5 hours during the service life before major repairs. The electric pump corresponds to the explosion-proof electrical equipment of group II with an explosion-proof level of explosion-protection, the temperature class of TK according to GOST R 51330.0-99, and the type of explosion protection-an explosive shell of the II subgroup in the software of GOST R 51330.1-99. Marking of the explosion protection of the electric pump 1EXDIIVTZH according to GOST R 51330.0-99. The electric pump is allowed to operate in explosive zones, classes 1 and 2, dangerous in conjunctional mixtures of categories II and IIV groups T1, T2 and TK according to GOST R 51330.13-99 according to Chapter 7.3 The Rules for the Installation of Electrical installations, ed. 6 1998 Climate execution and category of accommodation of an electric pump U* according to GOST 15150-69 In this case, the upper value of the ambient temperature is no more plus 40 C. The degree of protection against external influences IR68 GOST 14254-80.
