4: number of poles of the motor
Mat. Code: (TLHP-95) D37SSVQ
TLHP: Rotor code (TLHE = tri-lobe high
efficiency, TLHP = tri-lobe high pressure,
SCHE = scimitar high efficiency, SCHP =
scimitar high pressure)
95: temperature class of the pump (Deg. C)
D: type of couplings (D = DIN 11851, B = BSP,
E = DIN 2642, F = DIN 2576, R = RJT, S =
SMS, I = IDF, T = Tri-Clamp ISO2852, M =
Tri-clamp ASME BPE, O = Tri-clamp ISO, N =
ANSI flanges, V = DIN 11864-1, A = DIN
11864-2)
37: housing size of the NORD reductor
S: seal configuration (S = standard single seal,
Q = quench, D= double mechanical seal)
S: mechanical shaft seal materials (S = silicon
carbide / silicon carbide, I = carbon / stainless
steel, K = carbon / silicon carbide)
V: elastomer materials (E = EPDM, V = viton,
M = teflon, P = NBR)
Q: options (T = pump and motor reductor on
trolley, U = pump and motor reductor on
trolley with cover, P = bare shaft pump, Q =
pump and motor reductor aligned on base
plate, R = pump and motor reductor aligned
on base plate with cover, J = on pedestal
without foot)
Moreover, the year and week of construction, the
pump serial number (to be stated when ordering
spare parts), the weight, maximum operating
temperature and maximum differential pressure
are also marked on the name plate.
1.8 SOUND PRESSURE LEVEL
The sound-pressure level of the pump, operating
at 50Hz without cavitation measured at 1m is less
than 70dB(A). In order to minimize noise and
vibration, no other parts of the machine may
vibrate at the same time as the pump. The best
solution is therefore to allow the pump to rest
directly on the concrete floor, or to fit shock
absorbers between the pump and the frame of
the machine.
