2 Introduction IRON Pump /S was founded in 10 and since then the company has manufactured a great variety of pumps covering both the marine and industrial markets. Through the years the most popular pump type has been the split casing which has proven itself in many applications. It is impractical to cover all pump parameters in one brochure, so we have chosen only to describe models designed for fresh water and sea water within the marine and industrial markets. If an actual pump specification does not correspond to the parameters described in this brochure being pump medium, capacity, head, temperature, viscosity etc., the problem can often be solved by altering the split casing pump or by choice of another pump type. Notably, many split casing pumps have been delivered for up to bars of static pressure, for media temperatures up to 10 or for aggressive process media.

4 escription Type of pump orizontally or vertically mounted axial split casing centrifugal pump of single or multistage design. pplication resh and sea water applications in maritime and industrial service e.g. cooling water, ballast, fire fighting, heeling, district heating, public water supply, irrigation etc. Special features asy pump service where connecting pipes, driver and related installations remain untouched. Low NPS-value (good suction capability). Robust design with two outboard antifriction bearings. xially balanced rotating element giving longer bearing life. Pump Lay-out Impeller dimensioning On pages - the various sizes of pumps are shown with curves of relevant speeds and at max. impeller diameter (on the conditions given). To minimize power consumption and optimize the pump performance, all impellers are made to order with a diameter matching the desired duty point. The correct diameter, resulting in the desired capacity and head, can be calculated. With reasonable accuracy the following formula may be used: ydraulic balancing of split casing centrifugal pumps. apacity (m3/h): Q2 = Q1 2/1 ead (ml): 2 = 1 (2/1) 2 Power (kw): P2 = P1 (2/1) 3 Single stage design xially balanced by double entry impeller design. Two stage design xially balanced by back to back arrangement of two single entry impellers. Suct. isch. Suct. Suct. isch. Where as 1 is the original impeller diameter and 2 the new reduced diameter. The same formula may be used by replacing the impeller diameters with the pump speed. When the efficiency of the pump at duty point has been defined by using the actual standard pump curve the power consumption (at duty point) can be calculated using the following formula: resh Water: P kw = Sea Water: P kw = Qm3/h x ml 3,7 x η% P kw resh Water x Specific weight of the sea water 4

5 Priming s conventional centrifugal pumps are not able to evacuate air from, e.g. a suction pipe, it should be taken into account that a pump system, not flooded, must be primed before start-up. efore the size of the motor is defined the maximum power consumption of the pump must be taken into account. Suction In order to avoid cavitation it is important that the suction capability of the pump (NPSr) is better than the total available suction head of the application (NPSa) or this reason the actual standard curve of each pump shows the theoretical or measured NPSr-value of the pump, while the NPSa-value for the suction pipe system has to be calculated as the difference between the barometic pressure and the geometric and hydraulic resistance together with the partial steam pressure of the water. If the NPS-value of the pump is less than that of the suction pipe the system should work without cavitation. In practice the NPSr-value of the pump should be a minimum of 1 mlc less than the NPSa-value of the system. In all events caution should be taken not to start-up an empty pump as the shaft seals may be damaged. xplanation of Pump Type No: xample: irst letter Q=axial split casing type Second letter V = vertical (shaft) mounting = horizontal (shaft) mounting Third letter, if any P = priming pump incorporated = vertical pump with the impeller(s) mounted between the bearings ipher here, if any No cipher = one stage pump ipher 2 = two stage pump ipher 3 = three stage pump Number before the oblique 4 = 4 flanges (N0) 5 = 5 flanges (N5) - = flanges (N00) Number after the oblique Nominel impeller diameter in mm (not the maximum diameter) QVP-2-4/300 5

6 esign lements Shaft seal(s) Pump type QV is equipped with one mechanical shaft seal while type Q and QV contain two. The standard mechanical shaft seals are of the single seat type with a rotating carbon or silicium ring cast into a M, NR or PM rubber bellow and a stationary ceramic seat with a M, NR og PM o-ring. Spring and other metal parts are made of stainless steel. Special shaft seals - mechanical types such as cartridge and balanced, or conventional types with a wear sleeve for packing - are available upon request. lexible coupling The flexible coupling between motor and pump shafts is of the three part type, like a N-upex model. The coupling, made from cast iron and with flexible rubber elements, can be disengaged and allows for removal of the rotating element with removing the motor or disconnecting the pump from the piping system. Outboard bearings The pump shaft is equipped with two ball bearings, make S/, with external grease nipples. The bearings are designed for a minimum life of.000 running hours, at nominal speeds. Internal bearing bush Pump types QV and QVP are for pumping head pressures above 0 mlc equipped with an internal, media lubricated, synthetic sleeve bearing. lectric motor The pump design incorporates I standard motors from size 132 being the smallest on the 4 dia. pumps to size 400 as the largest on the dia. pumps. The motors are delivered according to the required power supply usually with IP protection and cooling according to I 411. Unless otherwise specified, the motor power will cover the maximum pump power consumption in accordance with N 1. rrangement of bearings and shaft seals in various types of split casing centrifugal pumps Type Q... oupling (half) all bearing Shaft seal Type QV... Test Impeller Wear ring Manually operated priming pump Possible bottom sleeve bearing Type QV... Impeller(s) mounted between the bearing (two shaft seals) Overhung mounted impeller(s) (one shaft seals) Type QVP... Pressure test fter machining, the casing parts are assembled and pressure tested with water, at a pressure minimum 0% of the duty pressure. Unless otherwise specified, the connection flanges are drilled in accordance with IN 21. apacity test efore delivery, the complete assembled pump and its driver is tested for capacity,

7 head and power consumption, in accordance with ISO 0-2. The test is made at 5- different duty points between 0 to 5-0% capacity, resulting in a pump performance curve. The pump efficiency is calculated at relevant duty point. dditional tests Upon request the following additional tests can be arranged: Pressure test acc. to special standard. apacity test acc. to special standard. Long run test (the time is specified by customer). NPS-test. Sound pressure test (not standardized). Overspeed test (of impeller). Paint thickness measurement. Painting actory standard painting The surface treatment of the approved pump is as standard: arefully cleaned. 1 x primer app. 30µ water based. 1 x covering top coat app. µ water based, grey (RL 7011). Special surface treatment cc. to customer wishes the pumps can be surface treated, e.g. lkyd or poxy internally as well as external according to specification. ocumentation Test certificates The results of the pressure, capacity and other tests are certified by the factory and the documents are delivered with the pumps together with other ordered certificates. Manuals s built manuals covering sectional drawing, spare part list and instructions for mounting, operation and repair are supplied in P format, unless otherwise specified upon order. 7
