INSTALLATION, OPERATION, The supply tank(s) should be large to allow dissolved air and other gases to escape from the liquid and allow LUBRICATION, MAINTENANCE AND suspended solids to settle out before entering pump. A system employing dams and settling chambers STORAGE INSTRUCTIONS is desirable.
Suction piping is often large, heavy (especially when a full size relief line. To minimize vibration (whether filled with liquid), and tends to vibrate. Proper solid hydraulic or mechanical), discharge lines should be supports are recommended. A suction hose located kept short, direct, well supported and solidly anchored.
Approx. Center Distance Deflection, (Span), inches inches Myers Aplex Series pumps utilize S.A.E. 40 wt. nondetergent oil in the crank case. This oil requires only a nonfoaming additive and should possess good 7/16 water separation (antiemulsion) character is tics. Such oils are often labeled “industrial”...
The drilled indentation on the bearing must be aligned with drilled and tapped hole in the back of the power Myers Aplex Series crankshaft suspension uses two frame. After the bearing is pressed into place, this single-row tapered bearings, which are shim adjusted indentation must approximately line up to allow use of to provide the correct running clearance.
Lube oil pump and filter assemblies are employed in Cups (outer races) of tapered roller bearings may be certain Myers Aplex Series pumps. This assembly is extracted from bearing carrier using a conventional installed after the shaft and its tapered bearings have bearing puller tool of the automotive type (widely been correctly set.
Crankpins that are worn out-of-round, tapered, or badly Replacement bushings are furnished prebored by scored should either be discarded or perhaps salvaged Myers Aplex Series which usually eliminates the need by grinding undersize, hard chrome-plated, and finish to ream the installed bushing bore. However, due to ground to above diameter.
Myers Aplex Series pumps all feature field removable Myers Aplex Series has developed a unique sealing set and replaceable stuffing boxes with plungers separable which operates on a hardened and ground stainless from the extension rods.
Spring-Guide Ring: Lantern rings are provided with O.D. and I.D. reliefs and two (or more) oil holes to allow lubricant to reach Plungers are heavy and the importance of a well-fitted the plunger. After the last unit of Styles 838 and 858 guide ring that carries this weight is often overlooked.
CONNECTING THE PLUNGER Myers Aplex Series can supply solid ceramic plungers on order. This plunger is very fragile, vulnerable to Install the metal baffle plate on the extension rod thermal and mechanical shock, and must be handled and roll the pump slowly until the extension rod male with the greatest care.
TROUBLE LOCATION AND REMEDY Trouble Possible Cause Remedy Pump fails to deliver Speed incorrect. Change drive ratio or tighten required capacity. Belts slipping. belts (if loose). Correct motor speed. Air leaking into pump. Seal with compounds. Liquid cylinder valves, Reface or lap valves and seats; seats or plungers worn.
