3.2 結構材料
結構適用的濕材料（接觸泵送溶液的部件）是FPP （填充玻璃纖維的聚丙烯）、PVC （聚 氯乙烯）、SAN、海帕倫、氟橡膠、特氟綸、316不銹鋼、PVDF （聚偏氟乙稀）、陶瓷和 碳合金。這些材料極耐大多數(shù)化學藥品。但是，有些化學藥品，如強酸或有機溶劑，會 使某些合成橡膠和塑料部件，如隔板、閥座或泵頭等老化。
3.2 結構材料（續(xù)）
有關化學相容性信息請咨詢耐化學性指南或供應商。
許多塑料、合成橡膠和泵設備生產(chǎn)廠家都出版了有助于選擇濕材料的準則，這些濕材料用于 泵送商用化學品和化合物。在使用合成橡膠或塑料部件來泵送化學藥品時，務必考慮兩個因 素。它們是：
? 工作溫度：溫度較高會提高化學藥品對濕材料的作用。增加的幅度因所使用的材料和化 學藥品而不同。在室溫下可以十分穩(wěn)定的一種材料，卻可能受高溫影響。
? 材料選擇：相同特性的材料，在受到某些化學藥品的影響時，它們彼此的性能可能會有 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.
