每臺電子計量泵都經試驗，符合規定的技術規范和**標準。
正確、小心地搬運、安裝和操作有助于確保無故障安裝。
? 搬運泵時要小心。跌落或重擊不僅會造成泵的外部損壞，而且還會損壞其內部電子部件。
? 泵安裝地點的環境溫度不能超過104°F (40°C)。泵可防水防塵，可用于室外，但是不能浸在 水中使用。不要在直射陽光下運行，防止泵的內部溫度升高。
IA小心 丨電磁線圈外殼、泵頭和泵殼可能高溫160°F(70°C),不可接觸。
? 泵的安裝地點要方便將來的維護和檢驗。泵要固定，避免振動。
? 在將管道安裝到閥門組件上之前，必須先卸下保護帽。使用規定尺寸的管道。將管道牢固地 連接到吸入端，防止外部空氣進入。確保排出端無液體泄漏。
? 小心檢查裝置電壓與計量泵數據標簽上指示的電壓是否-致。大多數型號的泵配有-個三叉 塞。務必確保計量泵接地。斷開連接時，不要拔電線，而是用手指夾住塞子，然后拔出。不 要使用與重型電氣設備共用的插座，重型電氣設備會產生沖擊電壓。沖擊電壓會使泵內的電 子電路產生故障。
?擅自改動電氣裝置有潛在危險。務必將化學藥品和泵裝置放在兒童不能接觸到的地方。
? 決不要在計量泵運行時修理或移動泵。-定要斷開電源。為了**，在操作化學計量泵或靠 近泵時務必穿戴防護服(防護手套和護目鏡)。
? 大多數.型號都配備帶有管接頭的放氣閥。啟動時，應在泵室內沒有流體時實施空氣吹掃。為 確保**，將回流管道連接到放氣閥，并使流體旁路回到儲槽或合適的排液管。
? 為了使體積輸出準確，泵必須在典型的運行條件下標定。
? 使用的化學藥品可能有危險，應小心按照標簽上的警告信息使用。遵守每種化學藥品的說明。 不要因為化學藥品相似而認為它們相同。務必將化學藥品儲存在**地點，遠離兒童和其他 人員。我們對誤用計量泵給送的化學藥品不負責任。務必將泵送流體的材料**數據表
(MSDS) 置于隨手可得 處。
?發運前已經用水對所有泵做了預試驗，如果用戶泵送的材料會與水起反應(即硫酸、聚合物), 應卸下泵頭，徹底干燥。閥座、球形閥、密封墊和隔板也應干燥。在投運泵前，應嚴格遵守 本程序。
? 閥芯上應壓印指示流體流向。安裝時一定要使箭頭朝著流量方向，從上到下閱讀標記。
? 計量危險材料時，不要使用塑料管，嚴格地使用合適的剛性管。有關專用適配器或閥門組件 信息請咨詢供應商。
?計量泵不可用于處理或計量易燃液體或材料。
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.
