・ 要防止堵塞或避免止回阀发生故障，请务必在吸入管末端安装套过滤器组件。这套底阀/过滤器组件务必安装在距离储罐底部上方1-2英寸（2-5 cm） 处，这样可以避免储罐底部可能积聚的固体堵塞过滤器。化学药品储罐和底阀/ 过滤器应定期清洗，确保连续**运行。如果溶液中周期性地沉淀出正在泵送 的化学药品，或者化学药品难以溶解或不能完全溶解（如氢氧化钙），则应在化 学药品储罐中使用混合器。这些在许多电动机配置和安装中都很容易提供。如 需要可与供应商联系。
箱内应包括：
－ 计量泵
－ 清洁挠性吸管*
－ 白色硬排出管*
－ 底阀/ 过滤器组件*
－ 背压喷射阀组件
－ 说明书
－ 放气阀组件*
－ 过滤器重物*
* 有无部件取决于型号。
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.
