? 要防止堵塞或避免止回閥發(fā)生故障，請(qǐng)務(wù)必在吸入管末端安裝套過(guò)濾器組件。這套底閥/過(guò)濾器組件務(wù)必安裝在距離儲(chǔ)罐底部上方1-2英寸（2-5 cm） 處，這樣可以避免儲(chǔ)罐底部可能積聚的固體堵塞過(guò)濾器。化學(xué)藥品儲(chǔ)罐和底閥/ 過(guò)濾器應(yīng)定期清洗，確保連續(xù)**運(yùn)行。如果溶液中周期性地沉淀出正在泵送 的化學(xué)藥品，或者化學(xué)藥品難以溶解或不能完全溶解（如氫氧化鈣），則應(yīng)在化 學(xué)藥品儲(chǔ)罐中使用混合器。這些在許多電動(dòng)機(jī)配置和安裝中都很容易提供。如 需要可與供應(yīng)商聯(lián)系。
箱內(nèi)應(yīng)包括：
－ 計(jì)量泵
－ 清潔撓性吸管*
－ 白色硬排出管*
－ 底閥/ 過(guò)濾器組件*
－ 背壓噴射閥組件
－ 說(shuō)明書(shū)

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.
