ATEX kimya diyaframlı pompaları, yağsız kimya diyaframlı pompaların tüm avantajlarını sunar. Tipik uygulamalar, potansiyel olarak patlayıcı ortamlara sahip döner buharlaştırıcılar ve kurutma fırınlarıdır. ATEX onayı, pompanın içini (pompalanan gazlarla temas halinde) ve pompanın çevresini içerir. Pompaların tüm ıslak parçaları mükemmel kimyasal dirence sahiptir ve esas olarak antistatik malzemelerden yapılmıştır. İnert gaz kullanımı için ayrı bir gaz balast bağlantı parçası teslimata dahildir.

Performans özellikleri

  • Olağanüstü kimyasal direnç ve üstün buhar toleransı
  • Doğrudan 230V / 50Hz tek fazlı güç kaynağı için entegre, kendinden kilitlenen aşırı yük ve aşırı sıcaklık korumalı aleve dayanıklı motor. Herhangi bir ek ve özel aşırı akım koruma cihazına gerek yok
  • Dahili ve çıkışta aşırı basınç emniyet tahliye vanaları
  • inert gaz tahliyesi ve diyafram kırılmasının tespiti için seçenekli emniyet diyafram teknolojisi

---------------------------------------------------

ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump. All wetted parts of the pumps have excellent chemical resistance and are mainly made of antistatic materials. Included in delivery is a separate gas ballast connection part for use of inert gas.

Performance features

  • outstanding chemical resistance and superior vapor tolerance
  • flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply. No need for any additional and specific overcurrent protection device
  • overpressure safety relief valves internally and at outlet
  • safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage
