Back pressure spring installation instructions
Metallic pump
The spring contained in this cloth bag is to be installed when this mroy pump will be discharging into an open tank or othersystem where the discharge back pressure is less than 50 PSIG.
The installation of this spring will assure repetitive metering accuracy under these conditions.
After pump has been fully primed according to the instruction manual,remove the cap from the body and insert this spring thruthe top seat to rest on top of the ball check, replace cap and tighteh until firmly seated on body.
Do not over-tighten,as o-ring provides the seal.
Do not insert spring in discharge ball cartridge on remote submerged head assemblies.
A separate back pressure valve must be installed in the discharge line from the remote head cartridge.
CAUTION: care must be taken when inserting the discharge pipe nipple into the ball check cartridge.
Nipple should not extend into cavity,causin

很高兴认识你，下次如果你还想翻译的话。我教你几种方法。在网站有www.HAO123.COM 这个网站的里有个上线翻译的 你可以好多种选择。日文 英文 。。。。。。很多很多种！就不用问别人 是不是很呢？ 希望你下次自己也能翻译！交个朋友可以吗？我叫小钟！
反压弹簧安装说明：
金属泵
当这种mroy泵被用来向泄荷反压力小于50PSIG的开口水箱或其他系统泄荷时，这个布袋包裹的弹簧将被使用。
这些弹簧的安装必须保证在这些状况下反复测量的准确性。
在泵依照说明书装好后，从泵身上去掉泵盖，插入弹簧使穿过顶部密封，保持这个状态，放上泵盖并让它和泵身紧紧密封。
在使用O型密封圈时不要过紧。
不要把弹簧插在移动的淹没的装配头上的泄荷球液压筒。
这个太难翻译了，只能翻译上面这些。
