低转速转子泵NVP，精密制造的转子泵
低转速转子泵NVP，也称为高粘度内齿泵，高粘度惰轮泵等用于，输送高粘度树脂,聚氨酯,聚谜,聚乙烯等类似的高粘度物料.
低转速转子泵NVP用途
特别适用高粘度稠度介质的输送。
泵头部、泵壳体、密封腔部分均可以带保温夹套。根据实际需要选择需要保温的位置。
夹套与泵体铸造成一体，保温效果良好，能够避免焊接夹套产生的各种问题。
需加热时：通过热蒸汽、导热油等各种热媒通入夹套腔即可进行保温。
需冷却时：通过各种冷却液，可以保持泵体的恒温。
低转速转子泵NVP结构
1．密封维修，更换，升级方便：保温转子泵NVP-B系列，轴承腔加大，轴承部分成为一个整体的部件，只需拧下顶丝即可旋下整个密封腔。密封可以从支架的轴承箱部分直接取下。这样不仅大大节省了维修的时间，更使维修变得更容易。
2．齿轮尾部间隙可调：高粘度转子泵NVP可以根据粘度的需要，通过调节齿轮间隙，达到泵在不同黏度下的工艺要求。整体轴承箱第二大优势就是，只需转动轴承箱即可实现间隙的调整。操作简单，不需拆卸泵的任何部件。
3．加大轴承腔第三大优势：宽大的支架腔提供的空间，不需拆泵，即可对填料进行调节。
4．部分重要部件可以根据工艺需要更换为各种耐高温、耐磨损、耐腐蚀、耐高压，和自润滑的材质。
5．整块材料坚固的铸造，避免了因振动、强外力等缘故造成对密封、轴承的影响。保证了泵输送的稳定性。
6．大流量泵可以实现高压下工作。
7．强有力的加粗轴保证了泵输送的稳定性。
8．保温夹套整体铸造，保温效果好，零泄漏。
9．多种耐高温填料密封，特殊材质、特殊设计，创造了填料密封胜过机械密封的奇迹。
高粘度转子泵NVP适用范围
广泛应用于各种流体的输送行业，尤其对于处理粘度变化较大、范围较宽的流体输送。
应用行业：适用于输送纯净且有一定粘度的流体，可用于输送油品如润滑油、原油等；也可以用来输送橡胶、沥青、油漆、粘合剂、染料、涂料、润滑剂、多元醇、食品、药品等不含颗粒性杂质的高粘度物料；还可用于输送PA PB PC PE PS HIPS ABS PP PET PVA等高温、高粘度聚合物熔体物料。
