Product Description

 
Product Description

Overview:

The DG is built to the latest edition of ISO13709(API610). It is a type BB5 horizontal, radially split, diffuser type, multistage barrel pump. The rotor stack can be either inline (all the impellers facing towards the driver) or Back-to-back. On the smaller pumps. The inboard seal chamber and bearing housing must be removed for cartridge removal. On larger pumps, the entire cartridge can be removed as anassembly to speed overhaul or re-rate turn around time.

The barrel is available as either acasting or forging with a variety offlange ratings to meet individual specifications.It is normally centerline supported for thermal stability and maximum nozzle load capacity. The barrel closure is either the traditional flanged head-studs and nuts, flanged head-Super nut Twistlock closure for speedy removaland assembly.

The inner cartridge consists of stacked diffuser/impeller sets. A double suctionfirst stage impeller is available on allbut the smallest sizes. Axial thrust is compensated by a balance drum forinline stacked rotors. The diffusers hydraulically balance radial forces. For those services where intermedia tepressure take off is needed, higher flow diffuser/impeller sets can be utilized upto the take off stage, and then lower flow sets are used after the takeoffstage to optimize efficiency and performance.When design conditions change, rerates are similarly achieve dusing different diffuser/impeller combinations, or blank stages all in thesame barrel.

For applications on light gravity fluid swith many stages, a back-to-back rotor stack is utilized to allow direct drive at normal motor speeds and provide improved rotor dynamics.In such rotorsthe opposed impellers cancel most of the axial thrust. The center bushing and throttle bushings take most of the residual axial thrust, so the thrust bearing loads are minimal. The back-to-back design allows the use of a7300 series ball thrust bearing andsaves the substantial cost and maintenance components associated with lube oil systems. For high pressure and high energy levels, inlineor back-to-back stack, high speed semi-stiff rotor designs are available.

Depending upon pump size, power and rotor design, the pumps can be supplied with ring oil or oil mistlubricated antifriction bearings, ring oil lubricated sleeve radial ball thrust bearings, or pressure lubricated sleeve radial-tilting pad thrust bearings.

Materials: All common ISO13709(API 610)material combinations are available.

Application

Thousands of DG pumps areinstalled around the world. They arefound in:
Power Plants
Refineries
Petrochemical Plants
Gas Processing Plants
Onshore and offshore water injection services
Onshore and offshore crude shipping services
Onshore crude oil, refined productand LPG pipeline services
High pressure and high or low temperatures are GSG services.

Pump structure

Inline and Back-to-Back Design Features and Benefits:

Inline:
Fulfills the majority of requirements for BB5 pumps with.either cast or forged barrels to meet customers pecifications.
Multivane diffusers balance radial loads. Balancing drum takes the majority of axial thrust load. Heavy duty bearings support the rotor and carry residual thrustloads.
Smaller size pumps fitted with ring oil lubricated antifriction bearings. Oil mist lubrication optional.
All but smallest sizes may be fitted with pressure lubricated sleeve radial, double acting tilting pad thrust bearings,lube oil systems, bearing RTD's,X-Y vibration probes and Keyphasor, etc.
Maximum number of inter changeable stage pieces minimizes spares parts inventory.
In direct drive applications, clearly the best selection upto stage limits. If still more head is needed, first consider GSG back-to-back and direct drive. If that does not meet head requirement, then consider GSG inline with higher speed-using gear box or VFD
For very high head and high energy levels beyond back-to-back direct drive capabilities,GSG with semistiff rotor design can be offered. Could justify stand-alone, single unit--nostandbv. Discussion recommended.

API 610 (BB5) Between Bearings, Diffuser Casing, Multistage Process Barrel Pump, Auxiliary (chemical) , Water and CO2 Injection, Crude, Product and CO2 PipelineBack to Back:
With up to 16 stages available, fulfills direct drive applications that require more head than is available from direct drive inline GSG
Multivane diffuserss balance radial load. Opposeo impellers balance majority of axial thrust. Center bushing and throttle bushing take nearly all theresidual axial thrust. Even when clearances are worn.axial and radial loads remain balanced.
Fan cooled, ring oil lubricated, sleeve/ball thrust bearing without lube systems are common up to ISO13709 (API 610) Table 9 limits, or limits depending upon application. Significantly reduces installed cost and provides simple, reliable pumps.
When even high speed GSG with semi-stiff inline rotor does not meet head requirements, or can not meet rotor dynamic requirements a GSG with semi-stiff backto- back rotor can be offered.

Rapid pump dismantling

To speed the repair of a GSG pump,larger sizes are designed using that cartridge concept. The pump coupling hub, inboard bearing housing, seal chamber and hydraulic cartridge slide through the barrel for quick removal. Re-installation is just as fast. For evenfaster turn around, the Twistlock design puts an end to hoursof torquing the barrel cover nuts. For remote locations or offshore this can be especially time and cost saving. Small GSG pump barrel bore are sosmall that the coupling hub, seal chamber and bearing housing will notfit through. Those parts have to be removed on those pumps before the cartridge is pulled.
