3.2 结构材料
结构适用的湿材料（接触泵送溶液的部件）是FPP （填充玻璃纤维的聚丙烯）、PVC （聚 氯乙烯）、SAN、海帕伦、氟橡胶、特氟纶、316不锈钢、PVDF （聚偏氟乙稀）、陶瓷和 碳合金。这些材料极耐大多数化学药品。但是，有些化学药品，如强酸或有机溶剂，会 使某些合成橡胶和塑料部件，如隔板、阀座或泵头等老化。
3.2 结构材料（续）
有关化学相容性信息请咨询耐化学性指南或供应商。
许多塑料、合成橡胶和泵设备生产厂家都出版了有助于选择湿材料的准则，这些湿材料用于 泵送商用化学品和化合物。在使用合成橡胶或塑料部件来泵送化学药品时，务必考虑两个因 素。它们是：
・ 工作温度：温度较高会提高化学药品对湿材料的作用。增加的幅度因所使用的材料和化 学药品而不同。在室温下可以十分稳定的一种材料，却可能受高温影响。
・ 材料选择：相同特性的材料，在受到某些化学药品的影响时，它们彼此的性能可能会有 很大不同。
PULSAtron Series E Plus Metering Pump
504 GPD @ 20 PSI, 230 VAC4-20 mA Input with Dual Manual Control and Stop Function Input
Stroke frequency control via 4-20 mA signal input, manual stroke length control. Stroke frequency is manually adjustable when in local control. Includes stop function input.
General Description
Pulsafeeder PULSAtron Series E Plus chemical metering pumps are positive displacement, diaphragm type pumps. Output volume is adjustable while pumps are in operation from zero to maximum capacity. The PULSAtron Series E Plus contains a highly reliable timing circuit as well as circuit protection against voltage and current upsets. This pump features solenoid protection by thermal overload with auto-reset. The Series E Plus guided check valves, with their state-of-the-art seat and ball designs, provide precise seating, and excellent priming and suction lift characteristics. Our timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances.
Pump Controls
Adjustment is by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are located opposite the liquid handling end. Automatic control via 4-20mA DC and stop function inputs. Auto-Off-Manual switch.
Drive Assembly
The pump drive is totally enclosed with no exposed moving parts. Electronics are housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption is 130 Watts.
Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant PBT thermoplastic. All exposed fasteners are stainless steel. Valve seat and seal ring are renewable by replacing the cartridge valve assembly.
