AP General purpose

Foot type CI gear pump with single helical gears and built in pressure relief valve.
This pumps works exceptionally well with applications were high temperature is your major concern. It can withstand temperatures up to 300 Degree Centigrade. The space occupied by this type of pump is very less.

APJ ( Steam jacketed pumps )

These pumps are specially suitable for liquids which solidify or become highly viscous at room temperature like LSHS, HHS, Glucose, Soap Stock, High Viscosity oils, Wax, Grease, Coal tar, Bitumen, Adhesives etc. Steam is circulated in the pump body to heat the liquid being pumped.

The information contained herein is of a general character and will be supplemented upon requested by specific instructions applying to the particular type of rotary pump being operated. It is requested that these instructions be placed in the hands of those directly charged with the installation and operation of the equipment. Satisfactory service can be realized only upon strict adherence of these instructions .

Checking Equipment

Inspect and check shipping manifest immediately on receipt of shipment and report any damage or shortage to the company.

Location

The pumps should be installed in alight, clean, dry location and so place that it is easily accessible for inspection. Suction piping should be full size, short and direct. Motor driven units should not be located in damp or moist places unless provision has been made for this condition.

Alignment

Correct alignment is absolutely essential for successful operation. A flexible coupling will not compensate for slight changes in alignments which may occur during normal operation.

Factory alignment

Every unit assembled at work is accurately aligned by placing the base plate on surface plate and then leveling the machined pads. Shims are inserted under the feet of the pump and driver when necessary to obtain perfect alignment. However, all base plates are elastics and for this reason we cannot assume responsibility for the proper mechanical operation of a unity unless the shop alignment is reproduced when the unit is erected on its foundation.

Field alignment

Pumps are usually shipped on their base plates and it is seldom necessary to remove the pump and driver from the base plate while leveling. The pumping unit should be placed on the foundation supported by wedges place near the foundation bolts. Remove the paint from the projections of the base plate pads upon which the pump feet are supported. Place a spirit level on these pads and adjust the wedges under the base plate to boring the pump to the shaft level.The alignment is then to be checked and corrected so as to bring the driver half coupling in perfect alignment with the pump half coupling. The checking of alignment can be accomplished by the use of a straight-edge across the top and sides of the coupling.If the coupling’s flanges are not perfectly true or not of the same diameter, check the alignment by revolving coupling and checking at each quarter turn. If any variation is found, proper allowance must be made in alignment the unit. The clearances between the coupling halves should be set so that they cannot strike, rub or exert end thrust on either pump or driver.

Important

Alignment must be checked after the pump has been completely piped up because pumps are frequently sprung and pulled out of position by drawing up flange bolts when the flanges are not squired up before tightening .Particular care must be taken that the suction and discharge piping is properly supported to prevent a strain or pull on the pump. Pipe strain are a common cause of misalignment, hot bearings, wear and vibration.

Grouting

The base plate should be grouted in before the piping connections are made. The usual mixture for grout is : one part cement and two parts sand with sufficient water cause the mixture to flow freely. The grout should be worked in under the base plate so as to support it fully throughout its whole area.

Suction Piping

Experience has proved that a faulty suction line is responsible for trouble with rotary pumps. Suction piping should never be less diameter than the full size of the pumps suction opening. It should be as short and direct as possible and thoroughly clean. It should be uniformly graded up form the source of the supply to the pump. When drawing liquid over long distances or on high suction lifts or when handling thick, viscous liquids, the diameter of the suction pipe should be greater then the opening in the pump to convey the liquid with minimum pipe friction loss.

Foundation

The foundation should afford permanent rigid supported for the entire unit.
Concrete foundation built up from solid ground will prove most satisfactory. Ample allowance should be provided for grout in building the foundation.
